Question

When the ice cubes are heated, the temperature at the melting point until the ice melts completely.

• A. increases
• B. decreases
• C. remains constant

Answer 1

The correct option is C remains constant

Until the entire ice melts, the temperature remains constant at the melting point. This is because the heat provided is used to overcome the intermolecular force of attraction and change the state from solid to liquid.

The amount of heat energy required to convert 1 kg of a solid into liquid at atmospheric pressure, at its melting point is called latent heat of fusion.
