If they are used, the walls and roof should be 10 inches thick to give the same protection as the 8-inch solid concrete blocks.

If a solid surface is chilled below the dew point of the surrounding air and the surface itself is colder than freezing, frost will form on the surface.

If the entire volume of the observable universe ( taken to be 3 × 10 < sup > 80 </ sup > m < sup > 3 </ sup >) were packed solid with fine dust particles about 1. 5 micrometres in size, then the number of different ways of ordering these particles ( that is, assigning the number 1 to one particle, then the number 2 to another particle, and so on until all particles are numbered ) would be approximately one googolplex.

If the cooling is sufficiently rapid ( relative to the characteristic crystallization time ) then crystallization is prevented and instead the disordered atomic configuration of the supercooled liquid is frozen into the solid state at T < sub > g </ sub >.

If the solid surface is rough, and the liquid is in intimate contact with the solid asperities, the droplet is in the Wenzel state.

If an isomorphism can be found from a relatively unknown part of mathematics into some well studied division of mathematics, where many theorems are already proved, and many methods are already available to find answers, then the function can be used to map whole problems out of unfamiliar territory over to " solid ground " where the problem is easier to understand and work with.

If every person now alive played one keno game every single second of their lives, there would be about one solid 20 jackpot-winning ticket to date.

If the latter subgroup cools slowly from a melt, it forms exsolution lamellae because the two components — orthoclase and albite — are unstable in solid solution.

If the structures of the two metals are the same, there can even be complete solid solubility, as in the case of electrum, the alloys of silver and gold.

If the energy transfer is more efficient to one of the target components, and / or it is less strongly bound to the solid, it will sputter more efficiently than the other.

If in an AB alloy the component A is sputtered preferentially, the surface of the solid will, during prolonged bombardment, become enriched in the B component thereby increasing the probability that B is sputtered such that the composition of the sputtered material will be AB.

If the solvent is a solid, then gases, liquids, and solids can be dissolved.

If the fingers are already flexed, then a solid bullet shows that they squeeze.

) If the vapor is in contact with a liquid or solid phase, the two phases will be in a state of equilibrium.

If a planet is sufficiently massive, the water on it may be solid even at high temperatures, because of the high pressure caused by gravity, as it was observed on exoplanets Gliese 436 b and GJ 1214 b.

If the domains are also aligned, the solid is a permanent magnet, which is magnetic even in the absence of an external magnetic field.

If the ions are not mobile, as in a solid salt then electrolysis cannot occur.

If, as observed in most cases, a substance is more dense in the solid than in the liquid state, the melting point will increase with increases in pressure.

If several spatially distributed charges generate such an electric potential, e. g. in a solid, an electric field gradient may also be defined.

It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces ; If the diameter of the tube is sufficiently small, then the combination of surface tension and forces of adhesion between the liquid and container act to lift the liquid.

If this route, virtually the only solid ground on which heavy cavalry could be effectively deployed, were to be denied to the English, they would have no choice but to wheel right to the north-east, on to the Carse.

If the husk is solid black, the seeds are called black oil sunflower seeds.

If the dying person cannot take solid food, the Eucharist may be administered in the " species " of wine alone, since the bread and wine are the Body, Blood, Soul and Divinity of Christ.

If the area is further reduced once the solid phase has been reached, collapse occurs, the monolayer breaks and soluble aggregates and multilayers are formed

If a litigant chooses to enforce a Federal right in a State court, he cannot be heard to object if he is treated exactly as are plaintiffs who press like claims arising under State law with regard to the form in which the claim must be stated -- the particularity, for instance, with which a cause of action must be described.

If, at any time during the assignment pass, the compiler finds that there are no more index words available for assignment, the warning message `` No More Index Words Available '' will be placed in the object program listing, the table will be altered to show that index words 1 through 96 are available, and the assignment will continue as before.

If the compiler finds that there are no more electronic switches available for assignment, the warning message `` No More Electronic Switches Available '' will be placed in the object program listing, the table will be altered to show that electronic switches 1 through 30 are available, and assignment will continue as before.

If the automorphisms of an object X form a set ( instead of a proper class ), then they form a group under composition of morphisms.

If this article / noun pair is used as the object of a verb, it ( usually ) changes to the accusative case, which entails an article shift in German – Ich sehe den Wagen.

If the object point be infinitely distant, all rays received by the first member of the system are parallel, and their intersections, after traversing the system, vary according to their perpendicular height of incidence, i. e. their distance from the axis.

If the object point O is infinitely distant, u1 and u2 are to be replaced by h1 and h2, the perpendicular heights of incidence ; the sine condition then becomes sin u ' 1 / h1 = sin u ' 2 / h2.

If, in an unsharp image, a patch of light corresponds to an object point, the center of gravity of the patch may be regarded as the image point, this being the point where the plane receiving the image, e. g., a focusing screen, intersects the ray passing through the middle of the stop.

If we look at this situation from far above, so that we cannot see the supporters, we see the large balloon as a small object animated by erratic movement.

If there be any party which is more pledged than another to resist a policy of restrictive legislation, having for its object social coercion, that party is the Liberal party.

If F and G are ( covariant ) functors between the categories C and D, then a natural transformation η from F to G associates to every object X in C a morphism in D such that for every morphism in C, we have ; this means that the following diagram is commutative:

If a pixel-by-pixel ( image order ) approach to rendering is impractical or too slow for some task, then a primitive-by-primitive ( object order ) approach to rendering may prove useful.

If a rotating frame is chosen so that just the angular position of an object is held fixed, more complicated motion, such as elliptical and open orbits, appears because the centripetal and centrifugal forces will not balance.

If there is a direct object, the indirect object can be expressed by an object pronoun placed between the verb and the direct object.

If the average density ( including any air below the waterline ) of an object is less than water it will float in water and if it is more than water's it will sink in water.

If the obstructing object provides multiple, closely spaced openings, a complex pattern of varying intensity can result.

If a particular object did not support a, it could be easily added in the module.

Frege, however, did not conceive of objects as forming parts of senses: If a proper name denotes a non-existent object, it does not have a reference, hence concepts with no objects have no truth value in arguments.

If the occulting object has an atmosphere, however, some of the luminosity of the star can be refracted into the volume of the umbra.

If a physical object statement is to be translatable into a sense-data statement, the former must be at least deducible from the latter.

Likewise, a functor from G to the category of vector spaces, Vect < sub > K </ sub >, is a linear representation of G. In general, a functor G → C can be considered as an " action " of G on an object in the category C. If C is a group, then this action is a group homomorphism.

If a laser is swept across a distant object, the spot of laser light can easily be made to move across the object at a speed greater than c. Similarly, a shadow projected onto a distant object can be made to move across the object faster than c. In neither case does the light travel from the source to the object faster than c, nor does any information travel faster than light.
