Question

Which of the following statements are true of thermal energy and kinetic energy?

Check all that apply.

Answer 1

Letters A and D appear to be correct.

Answer 2

A) All molecules or atoms in motion have kinetic energy

B) Each molecules or atom in motion have kinetic energy

C) Each molecule or atom in motion have thermal energy

D) All molecules or atoms in motion have thermal energy

Step-by-step explanation:

As we know that kinetic energy is given as

`KE = (1)/(2)mv^2`

now we know that if all molecules are in motion then due to their motion the energy stored in it is given as kinetic energy

now we also know that thermal energy is the sum of kinetic energy of all atoms or molecules so it is given as

`KE = (3)/(2)nRT` = thermal energy

so correct statements are

A) All molecules or atoms in motion have kinetic energy

B) Each molecules or atom in motion have kinetic energy

C) Each molecule or atom in motion have thermal energy

D) All molecules or atoms in motion have thermal energy
