Question
Assuming water molecules in the gasphase act as an ideal gas, how many times greater is the rms speedof water molecules in the gas phase at the boiling temp ofwater compared to the freezing temp of water a-5,000 x as fast b-2,236 " " c-1,366- " " d-1,169 " " e you cannot divide by zero HELP!!!!!!!!!!!!!!!!!!!

Explanation / Answer
Rms speed v = [ 3RT / M ] from this v T Or ( v ' / v ) = [ T ' / T ] Given T ' = boiling temperature = 100 oC =100 + 273 = 373 K T = freezing temperature = 0 oC = 0 + 273 = 273 K So, v ' / v = [ 373/273 ] = 1.16888 ~1.169
