1.	(i) What is he effect of temperature on (a) density, (b) surface tension , (c) visocity and (d) vapour pressure of a liquid ? (ii) What is the effect of pressure on (a) volume, (b) boiling point and (c) viscosity of a liquid ?
Answer» SOLUTION :(i) (a) Density DECREASES (b) surface tension decreases (c) Viscosity decreases (d) Vapour pressure INCREASES with rise in TEMPERATURE. (ii) (a) Volume decreases (b) B. pt increases (c) Viscosity increases with INCREASE in pressure.
