Show answer and explanation

Answer: C. More kinetic energy

The correct answer is C. More kinetic energy. When a liquid is heated, its molecules absorb energy and move faster, so their kinetic energy increases. The molecules also move further apart, so the intermolecular space increases and the attraction decreases.
