Question

Heat absorbed during change of phase depends on ______ of the substance.

Options

• mass

• change in temperature

• specific heat capacity

Answer 1

Heat absorbed during change of phase depends on mass of the substance.

Explanation:

The heat absorbed during a phase transition, such as melting or boiling, depends on the mass of the substance. During a phase transition, the temperature remains constant; thus, the heat absorbed is directly proportional to the mass (Q = mL), rather than the temperature variation.
