Arturo Galvan · Answer 1

H. Cube A has more thermal energy than cube B.

Explanation:

Since both cubes are at 5 °C. It means both cubes have same temperatures.

This is because temperature is independent of the amount of system.

Thermal energy however is a function of the amount of the system. thermal energy is the total kinetic energy of particles of matter. Since Cube A is larger, it means that cub A has a higher thermal energy than cube B.

The correct option is;

H. Cube A has more thermal energy than cube B.
