94. A solution is made by dissolving 1 kilo mole of solute in 2000 kg of solvent. The molality of the solution is
95. If the partial pressure of the solvent in the vapor phase is equal to the vapor pressure of the solvent at that temperature, then the system is said to be at its
96. If the pressure of a gas is reduced to half & its absolute temperature is doubled, then the volume of the gas will
97. Disappearance of snow in subzero weather exemplifies the process of
98. At 100°C, water and methylcyclohexane both have vapour pressures of 1 atm. Also at 100°C, the latent heats of vaporisation of these compounds are 40.63 kJ/mole for water and 31.55 kJ/mole for methylcyclohexane. The vapour pressure of water at 150°C is 4.69 atm. At 150°C, the vapour pressure of methylcyclohexane would be expected to be
