# If P, then Q.

# If isotherms are concave towards the " north-east " direction ( 45 °), then adiabats are concave towards the " east north-east " ( 31 °).

# If adiabats and isotherms are graphed severally at regular changes of entropy and temperature, respectively ( like altitude on a contour map ), then as the eye moves towards the axes ( towards the south-west ), it sees the density of isotherms stay constant, but it sees the density of adiabats grow.

# If morality is objective and absolute, God must exist.

# If the beat on the new record hits before the beat on the current record then the new record is too fast, reduce the pitch and manually slow the speed of the new record to bring the beats back in sync.

# If the beat on the new record hits after the beat on the current record then the new record is too slow, increase the pitch and manually increase the speed of the new record to bring the beats back in sync.

# If equals are added to equals, then the wholes are equal.

# If equals are subtracted from equals, then the remainders are equal.

# If the remainder from dividing N by 6 is not 2 or 3 then the list is simply all even numbers followed by all odd numbers ≤ N

# If the remainder is 2, swap 1 and 3 in odd list and move 5 to the end ( i. e. 3, 1, 7, 5 )

# If the remainder is 3, move 2 to the end of even list and 1, 3 to the end of odd list ( i. e. 4, 6, 8, 2-5, 7, 9, 1, 3 )

# If the design is symmetrical in an axis parallel to the flag pole, obverse and reverse will be identical despite the mirror-reversal, such as the Indian Flag or Canadian Flag

# If not, the obverse and reverse will present two variants of the same design, one with the hoist on the left ( usually considered the obverse side, see flag illustrations ), the other with the hoist on the right ( usually considered the reverse side of the flag ).

# If two straight lines in a plane are crossed by another straight line ( called the transversal ), and the interior angles between the two lines and the transversal lying on one side of the transversal add up to less than two right angles, then on that side of the transversal, the two lines extended will intersect ( also called the parallel postulate ).

# Associativity: If a * b and b * c are defined, then ( a * b ) * c and a * ( b * c ) are defined and equal.

# Identity: If a * b is defined, then a * b * b < sup >− 1 </ sup >

# If it persists, " gather facts and seek help.

# If the noun is animate, natural gender tends to dictate grammatical gender.

# If the borrowed word happens to have a suffix that the borrowing language uses as a gender marker, the suffix tends to dictate gender.

# If the borrowed word rhymes with one or more native words, the latter tend to dictate gender.

# If a project's spending becomes too much for a committee to continue funding, it must take the issue to the Project Committee.

# Affordable premium: If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that the insurance will be purchased, even if on offer.

# If the German Armed Forces ( Wehrmacht ) were not in a position to break the danger from the Eastern front, then Nazi Germany would fall to Bolshevism, and all of Europe would fall shortly afterward ;

# Some of the contents of the container are then blended until liquid, depending on the desired consistency.

# The remaining contents of the container are added to the liquid, then briefly puréed until there is some texture remaining for garnish.

# The internal field of the Earth ( its " main field ") appears to be generated in the Earth's core by a dynamo process, associated with the circulation of liquid metal in the core, driven by internal heat sources.

# A free worker cannot sell his human capital in one go ; it is far from being a liquid asset, even more illiquid than shares and land.

# Pressing: The fully fermented grain slurry is placed into cloth-lined containers and pressed to separate the solids from the liquid soy sauce.

A leak was detected between the liquid oxygen dome and injector for the # 4 H-1 rocket engine ; while attempts were made to fix the problem, it was eventually decided to launch without replacing the engine.

# Photometry / Spectrophotometry When the absorbence of a specific wavelength of light while passing through a fixed path-length through a cuvette of liquid test sample is measured and the absorbance is compared with a blank and standards with graded amounts of the target compound.

# Transmittance of light may be used to measure e. g. clearing of opacity of a liquid created by suspended particles due to decrease in number of clumps during a platelet agglutination reaction.

# Turbidimetry when the opacity of straight-transmitted light passing through a liquid sample are measured by detectors placed straight across the light source.

# REDIRECT drop ( liquid )

# Compressed gas storage — The oxygen gas is compressed in a gas cylinder, which provides a convenient storage, without the requirement for refrigeration found with liquid storage.
