In part PQ, the state is liquid and temperature is decreasing, In part QS there is change of state from liquid to solid, i.e., this stage is freezing, without change in temperature. In part ST, state is solid and temperature is decreasing with time.

Based on the statements given here choose the correct answer. (1) Boiling point of a liquid increases with increase in temperature. (2) The volume of liquids increases on boiling and the vaporisation curve shows the variation of the boiling point of a liquid with pressure and expands the equilibrium state between liquid and vapour phase.
The phase transition in which a liquid turns into a solid, when its temperature is lowered below its freezing point, is called as _________.
Sort the processes for the following changes in phase given below from bottom to top. Solid→Gases→Liquid→Solid→Liquid
At point D (273.16K,0.006atm) all there phases of water coexist. Observed phase change when the temperature is increased from−100Cto+100C, at a constant pressure of 0.006 atm is.
