Understanding +4 | -1

Statement 1: When a solid melts of a liquid boils, the temperature does not increase when heat is supplied.
Statement 2: The heat supplied is used to increase internal kinetic energy.

View answer and explanation

Correct option: B

Statement 1 is true and statement 2 is false

Option B is correct because during a phase change, the heat supplied is used to overcome intermolecular forces, not to increase kinetic energy (and thus temperature).
