If you do use a cold frame be sure that its ventilation is adequate.

If a normally biennial plant is grown in extremely harsh conditions, it is likely to be treated as an annual because it will not survive the winter cold.

If buried where the earth is very cold, the earth acts like a refrigerator.

If gelatin is put into contact with cold water, some of the material dissolves, but not all.

If confirmed, this would indicate that such symmetric fusion reactions should be modelled as ' hot fusion ' reactions rather than ' cold fusion ' ones, as first suggested.

* In the second verse of the hit song " Rocket Man " ( 1972 ), Elton John sings " Mars ain't the kind of place to raise your kids / In fact it's cold as hell / And there's no one there to raise them / If you did ".

If a pub served meals they were usually basic cold dishes such as a ploughman's lunch.

If the SEM is equipped with a cold stage for cryo-microscopy, cryofixation may be used and low-temperature scanning electron microscopy performed on the cryogenically fixed specimens.

" I do not refer to real estate, or to personal property or to cold cash, but rather to that in life which tends to make these tangible substances count for most in the daily lives of people, namely, goodwill, fellowship, mutual sympathy and social intercourse among a group of individuals and families who make up a social unit … If he may come into contact with his neighbor, and they with other neighbors, there will be an accumulation of social capital, which may immediately satisfy his social needs and which may bear a social potentiality sufficient to the substantial improvement of living conditions in the whole community.

If the cold front is active enough to produce thunderstorms, anvil cirrus clouds may spread ahead of the front as a warning of its approach.

* If one hand is immersed in cold water and the other in hot for a minute or so, and then both hands are placed in lukewarm water, the lukewarm water will feel hot to the hand previously immersed in cold water, and cold to the hand previously immersed in hot water.

If volatile reactants are involved the reactants are often put in an ampoule that is evacuated-often while keeping the reactant mixture cold e. g. by keeping the bottom of the ampoule in liquid nitrogen-and then sealed.

If blood is taken from a hibernating squirrel in the winter and injected into another squirrel in the spring, the normally active squirrel will be more prone to hibernation when placed in cold dark conditions.

If a pub served meals they were usually basic cold dishes such as a ploughman's lunch.

If visiting in winter it is a good idea to bring warm clothes because at such a high altitude the region experiences frequent snow falls and cold temperatures.

If it is too cold, electrically conductive deposits may form on the insulator causing a loss of spark energy or the actual shorting-out of the spark current.

If exposed to cold and the internal mechanisms are unable to replenish the heat that is being lost, a drop in core temperature occurs.

If it is seen after rain it should clear due to warm front succession, but if this does not occur the stratus must be part of the warm sector of a frontal system ; heavy rain may start again with the arrival of a cold front after several hours of stratus.

If the temperature is above the material's recrystallization temperature it is deemed hot forging ; if the temperature is below the material's recrystallization temperature but above 30 % of the recrystallization temperature ( on an absolute scale ) it is deemed warm forging ; if below 30 % of the recrystallization temperature ( usually room temperature ) then it is deemed cold forging.

If the alteration in the sense of taste is due to gum disease, dental plaque, a temporary medication, or a short-term condition such as a cold, the dysgeusia should disappear once the cause is removed.

If the muscles contract more than normal, for example in cold weather, the blood vessels also contract so that less blood passes through them, and also reduces the loss of body heat.

If I clean it up they'll catch a cold from the cleanliness ".

If the target can change its position significantly during the 30 minutes the missile is in the air on its way, the probability of the missile destroying the target is drastically reduced.

If your house is to have a forced warm air system, cooling can be a part of it.

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 collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter, appearing blue as a result.

If the holes are closed, the gas will only mix with ambient air at the point of combustion, that is, only after it has exited the tube at the top.

If the combustion takes place using air as the oxygen source, the nitrogen can be added to the equation, as and although it does not react, to show the composition of the flue gas:

If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w. While air mass identification was originally used in weather forecasting during the 1950s, climatologists began to establish synoptic climatologies based on this idea in 1973.

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 air is heated in a region it will expand in all directions such that the velocity field points outward from that region.

If the air cools and contracts, the divergence is negative and the region is called a sink.

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 extension is executed properly the discus will be at the right angle to ride on the air current and thus be taken a farther distance.

If a larger fire is necessary, the smith increases the air flowing into the fire as well as feeding and deepening the coke heart.

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 indoor air is very humid, rather than moderately so, water will first condense in small droplets and then freeze into clear ice.

If the vocal folds are drawn apart, air flows between them causing no vibration, as in the production of voiceless consonants.

If too much water and not enough air surrounds the plants roots, it is possible to gradually lower the medium's water-retention capability by mixing in increasing quantities of perlite.

The valuation of the Koh-i-Noor is given in the legend that one of Nader Shah's consorts supposedly said, " If a strong man should take five stones, and throw one north, one south, one east, and one west, and the last straight up into the air, and the space between filled with gold and gems, that would equal the value of the Koh-i-noor.

If the fluid is air, the force is called an aerodynamic force.
