(a) The density of water at 0ºC is very nearly 1000 kg/m3(it is actually 999.84 kg/m3), whereas the density of ice at 0ºC is 917 kg/m3 .Calculate the pressure necessary to keep ice from expanding when it freezes, neglecting the effect such a large pressure would have on the freezing temperature. (This problem gives you only an indication of how large the forces associated with freezing water might be.) (b) What are the implications of this result for biological cells that are frozen?

If you place 0 ice into 0 water in an insulated container, what will the net result be? Will there be less ice and more liquid water, or more ice and less liquid water, or will the amounts stay the same?
Consider the pressure of a height of 10 km in a volume of air, M = 0.0289 kg/mol. If the pressure at ground level remains at 1 atm but the temperature changes from 300K to 320K, what will be the change in pressure at 10 km altitude?

The brass scale of a mercury barometer gives the correct length of the mercury column at 0°C. IF the barometer reads 740mm at 25°C, which is the reading when corrected for expansion of brass scale and for the expansion of the mercury (which decreases its density). (include FBD)
Why does rubbing alcohol evaporate much more rapidly than water at STP (standard temperature and pressure)?
Consider 2.00 L of air in a patients lungs at 37.0 degrees celsius and .800 atm pressure. What volume would this air occupy if it were at 25 degrees celsius and under a pressure of 250 atm?
Water oozes out from a porous pot , the pressure inside being 20 atmospheres more than that outside. If the temperature of water inside be 10 degree C , what would it be on coming out?
Show that the coefficient of area expansion, (∆A/A)/∆T, of a rectangular sheet of the solid is twice its linear expansivity, α1.
In an ultrahigh vacuum system (with typical pressures lower than 10-7 pascal), the pressure is measured to be 1.00 x 10-10 torr (where 1 torr = 133 Pa). Assuming the temperature is 310 K, find the number of molecules in a volume of 1.00 m3.
You buy an "airtight" bag of potato chips packaged at sea level, and take the chips on an airplane flight. When you take the potato chips out of your "carry-on" bag, you notice it has noticeably "puffed up." Airplane cabins are typically pressurized at 0.90 atm, and assuming the temperature inside an airplane is about the same as inside a potato chip processing plant, by what percentage has the bag "puffed up" in comparison to when it was packaged? Express your answer using two significant figures. (V2−V1)/V1= ?
By how much does the volume of gas at 0°C contract for each decrease in temperature of 1 Celsius degree when the pressure is held constant?
