Which of the following is INCORRECT for water? A. Freezing point temperature decreases with increasing pressure. B. Solid is less dense than liquid C. Water has an unusually high boiling point temperature. D. Vapor pressure is equal to 1 ATM at 100 degrees Celsius. E. Solid can't be converted directly to a vapor, it must first melt, then vaporize.

Explanation / Answer

option A is correct as pressureinc. the F.P dec. Option B. solid is less dense than liq as solid ice as .7 density and ice as almost 1. C. correct this nature of wate is due to hydrogen bonding present in the water, Vapour Pressure is atm at 100 degrees as water starts boling at 100 degree and pressure of vapour become as same as atmosphere. but in option E. dry ice can directly converted to vapour form or if we increase the Freezing point we seee that there is is a gas which libratesout of the ice , in cold places it is seen that snow liberates gas when the temprature is very low.
