Question

when the temperature of the solids is increased for the constituent molecules ?
i.The potential energy remains same and the kinetic energy increases
ii.both increases.
iii.the potential energy decreases and kinetic energy increases
plss reply fast i have exam tomorrow and explain ​

Answer 1

Answer:

(ii) is correct answer.

Explanation:

When the temperature of the solid is increased, the constituent molecules move rapidly their vibratory motion increase so the kinetic energy of the molecule increase, increase in temperature also apply force on the molecules so they move, which let to the work done by the molecules, work done is accompanied by increase in potential energy. so both the kinetic energy and potential energy increase.
