36. The effect of pressure on the heat capacity of the gases __________ is negligible.
39. 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
40. One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m3. It cools to 98°C; the saturation pressure is 0.943 bar; one kg of water vapour under these conditions has a volume of 1.789 m3. The amount of water vapour condensed (in kg) is
41. A 'limiting reactant' is the one, which decides the __________ in the chemical reacation.
42. If the pressure of a gas is reduced to half & its absolute temperature is doubled, then the volume of the gas will
