2. Liquid B because as pressure increases the boiling point also increases
3.when we apply pressure on any gas the particles of gas come closer and thus changing into liquid state
4.LPG and oxygen
5.because as the surface area increase the evaporation increases . Thus in saucer due to larger surface area the milk or tea becomes cooler faster and thus we can drink it easily as evaporation causes cooling
