physics questions
1,the average kinetic energy of a molecule in a liquid_______
a)gets larger when temperature increases
b)doesn't change when temperature increase
2,why does warm water evaporate faster than cold water?
a)energy needed to break a molecule out of the surface of water is less if the water is warmer
b)molecules move faster in warm water than in cold water
3,waht is the main reason that you feel warmer on a hot humid day than on a hot dry day?
a)the extra moisture makes air conduct heat better
b)the extra moisture gives air greater heat capacity
