If you have a house which heat doesn't penetrate easily, your unit will have less heat to remove.

If the brine regenerator uses high heat, they also partially sterilise the air.

If enough electric power is available, cooling can be provided by conventional air conditioning using a heat pump.

If the pressure in a system remains constant ( isobaric ), a vapor at saturation temperature will begin to condense into its liquid phase as thermal energy ( heat ) is removed.

If the heat of vaporization and the vapor pressure of a liquid at a certain temperature is known, the normal boiling point can be calculated by using the Clausius-Clapeyron equation thus:

If later heat treatments cause this glass to become partly crystalline, the resulting material is known as a glass-ceramic, widely used as cooktop.

If high output powers are needed from a class-A circuit, the power waste ( and the accompanying heat ) will become significant.

If ΔH is positive, the reaction is endothermic, that is heat is absorbed by the system due to the products of the reaction having a greater enthalpy than the reactants.

If FLARE provided the XM-291 gun project with the sufficient radiative heat to ignite the propellant to achieve a muzzle energy of 17 MJ one could only imagine the possibilities with a fully developed FLARE plasma igniter.

If buried on hot coals or ashes, the heat can kill pathogens, the dry ash can desiccate, and the earth can block oxygen and further contamination.

If water is evaporated too quickly, the membrane dries, resistance across it increases, and eventually it will crack, creating a gas " short circuit " where hydrogen and oxygen combine directly, generating heat that will damage the fuel cell.

If the meteoroid maintains a fixed orientation for some time, without tumbling, it may develop a conical " nose cone " or " heat shield " shape.

If these delayed neutrons are captured without producing fissions, they produce heat as well.

If water-saturated zones still exist in sediments under the volcano, they would likely have been kept warm by a high geothermal gradient and residual heat from the volcano's magma chamber.

If a supercontinent covers a portion of the earth ’ s surface where heat from the mantle accumulates under the crust, it causes the land mass to dome upward.

If the appliance is one whose purpose is for light or heat ( such as an incandescent lightbulb or electric oven ) then the lighting or heating elements may be considered as a type of fire ; if so, then turning them on constitutes both " lighting a fire " ( category 37 ) and " cooking " ( a form of baking, category 11 ), and turning them off would be " extinguishing a fire " ( category 36 ).

If the friction and heat dissipation were not present, the Moon's gravitational force on the tidal bulge would rapidly ( within two days ) bring the tide back into synchronization with the Moon, and the Moon would no longer recede.

If the current is large enough to generate more heat than the device can lose to its surroundings, the device heats up, causing its resistance to increase, and therefore causing even more heating.

If too many of these neutrons are absorbed by other uranium-235 nuclei, a nuclear chain reaction occurs that results in a burst of heat or ( in special circumstances ) an explosion.

If " carb-icing " is an issue, plenty of waste engine heat is available to prevent trouble.

If you put heat as a product:

If we were to lower the temperature, the equilibrium would shift to produce more heat.

If these measures are insufficient to make the blood temperature in the brain match the new setting in the hypothalamus, then shivering begins in order to use muscle movements to produce more heat.

If the armor is defeated, the heat and spalling ( particle spray ) generated by the penetrator going through the armor, and the pressure wave that would develop, would destroy the target.

If she did, he could stand it better in the light.

If the input light distribution falls beyond the visible range, Af as expected, since Af.

If it pleases symphony audiences as a light, jolly piece, a series of impressions musically expressed, it succeeds.

If light moves instantaneously, the telescope does not move, and the true direction of the star relative to the observer can be found by following the line ES.

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 appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called " black ".

If the source emits light uniformly in all directions, the flux can be found by multiplying the intensity by 4π: a uniform 1 candela source emits 12. 6 lumens.

If it is removed, the light ceases.

If the glass is cooled quickly in the absence of a strong light source by putting ice on the glass or placing it in the freezer with the door almost closed, it turns backwards ( i. e. the silver sides trail ).

If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin.

If the incident light is monochromatic, these sources all have the same phase.

If light consisted strictly of ordinary or classical particles, and these particles were fired in a straight line through a slit and allowed to strike a screen on the other side, we would expect to see a pattern corresponding to the size and shape of the slit.

If the width of the slits is small enough ( less than the wavelength of the laser light ), the slits diffract the light into cylindrical waves.

If the width of the slits is greater than the wavelength, the Fraunhofer diffraction equation gives the intensity of the diffracted light as:

If a ray tracing is then made as if a light wave ( as understood in classical physics ) is wide enough to take both paths, then that ray tracing will accurately predict the appearance of maxima and minima on the detector screen when many particles pass through the apparatus and gradually " paint " the expected interference pattern.

If the emulsion is dilute enough, higher-frequency and low-wavelength light will be scattered more, and the emulsion will appear bluer-this is called the " Tyndall effect ".

If applied to optical wavelengths, this manifests itself as a change in the colour of visible light as the wavelength of the light is increased toward the red part of the light spectrum.

If the incident light is unpolarised ( containing an equal mix of s-and p-polarisations ), the reflection coefficient is

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.

If Lorentz symmetry can cease to be a fundamental symmetry at Planck scale or at some other fundamental scale, it is conceivable that particles with a critical speed different from the speed of light be the ultimate constituents of matter.
