Kinetic energy is …………to temperature.
a) directly proportional
b) inversely proportional
c) has no effect
d) none of these
Greater the temperature ……………. will be evaporation.
a) higher
b) lower
c) much lower
d) b & c both
Explanation:Higher the temperature, more molecule will gain the kinetic energy and will be available for escape from the surface to evaporate.
Evaporation rate decreases as………will be intermolecular forces.
a) weaker
b) stronger
c) much weaker
d) has no effect
Explanation:Greater will be the intermolecular forces, molecules will be bound to escape so the rate of evaporation will be low.
Water has ………intermolecular forces than alcohol.
a) lower
b) higher
c) much higher
d) none of these
Alcohol has ………….. rate of evaporation than water.
a) higher
b) lower
c) both a & b
d) much lower
Explanation:Alcohol has lower intermolecular force than water so it will evaporate quickly.
The pressure exerted by the vapors in equilibrium state is called ………….
a) vapor pressure
b) atmospheric pressure
c) liquid pressure
d) all of these
