Question

practice it! the ice cube and the frozen lake are both the same temperature, 0°c. what is true about their thermal energy? select the correct answer. they have the same thermal energy. this is because they are the same temperature. the frozen lake has more thermal energy. it is composed of more water molecules and has more mass. they have different thermal energy. this is because they are the same temperature. the ice cube has more thermal energy. it is composed of fewer water molecules and has less mass.

Explanation:

Thermal energy depends on mass and temperature. Since both the ice cube and the frozen lake are at \(0^{\circ}C\) (same temperature), but the frozen lake has a much larger mass (more water molecules), it has more thermal energy.

Answer:

The frozen lake has more thermal energy. It is composed of more water molecules and has more mass.
