Question

3. Which statement is not consistent with the information contained in the phase diagram of a compound? A. Liquids can be made to boil by raising the pressure at constant temperature. B. Solids can be made to melt by raising the temperature at constant pressure. C. Gases are most likely to be found at high temperatures and low pressures. D. The boiling point of a compound is the temperature at which the vapor pressure of the compound is equal to atmospheric pressure. E. All of these statements are consistent with the information in the phase diagram of a compound.

Explanation / Answer

The non consistent statemnt is A.

A.) On increasing the pressure of liquid at constant temprature, it will not boil.Because on increasing the pressure the molecules of liquid will come further closer to eachother which is opposite to the behaviour of molecules in the gaseous state. In gaseous state molecules are far away from one another.

So as to boil the liquid we should employ a method such that it takes the molecule further away.

This can be achieved by DECREASING THE PRESSURE AT CONSTANT TEMPRATURE
