What happens to pressure at different temperatures?

Pressure (such as air in a balloon) can increase with higher temps and decrease with lower temps.


Are infrared rays absorbed by the ozone layer which protects the earth?

Far infrared rays are, corresponding to lower temperatures, but not near infrared which corresponds to warmer temps.


How can bowens reaction series determine the silica content in magma?

Higher silica contents will be in the igneous rocks that form with lower temps. Ones that form earlier in the series like olivine have lower percentages of silica.

Why the temperature of agar must be no lower than 45 c and no higher than 50 c?

Below 45 the agar begins to solidfy and above 50 the bacteria can bekilled. If you are adding anything to the media, such as antibiotics, etc.,some of these can be inactivated at temps higher than 50.

What temps do tornadoes happen?

There are no specific temperatures at which a tornado occurs. They typically occur with temps in the 60s and 70s, but can occur at warmer or much cooler temps. The main aspect is not what the temperature is, but how much instability (availability for rising air) and wind shear (change in wind direction and speed with height in the atmosphere) is present.


What temperature is optimal for alcoholic fermentation in yeast?

Most sources agree on a range between 20 and 30 celsius. 20C is 68F, 25C is 77F and 30C is 86F. Some claim that the lower end of the scale is better, some claim the upper to be better. Playing it safe would place you in the middle, or 25C (77F). Temps lower than 20C will slow the yeast's ability to produce alcohol, and higher temps, such as 35C (95F) will kill the yeast entirely.


Why does moisture come down as ice instead of snow in temps of 20's?

Because the temperature higher in the atmosphere is above freezing, allowing snowflakes to melt into ice. If you're experiencing sleet (ice pellets), that meanst that there is a fairly thick layer of subfreezing air at the surface, allowing the rain to freeze back into ice pellets. If rain is falling and freezing on contact (freezing rain), that means the cold layer at the surface is shallow and the rain has no time to freeze before reaching the surface. It then freezes on contact with cold surfaces, forming a glaze of ice.
