Description

Phase Changes

When a solid is heated, it eventually melts into a liquid. Similarly, when a liquid is heated, it boils into a gas. During these processes, the temperature remains constant despite the addition of heat energy.

  1. a

    State the process that occurs when a solid turns into a liquid.

    Aim for approximately 1 distinct marking point.
