What happens to the heat supplied to a substance when the heat supplied causes no change in the temperature of the substance ?

Explanation

### Step-by-Step Solution:

1. **Understanding Heat Transfer**: When heat is supplied to a substance, it can lead to a change in temperature or a change in phase (state of matter).

2. **Identifying No Temperature Change**: In this scenario, we are specifically looking at the situation where the heat supplied does not cause any change in temperature. This means that the temperature change (ΔT) is equal to zero.

3. **Defining Latent Heat**: The heat that is supplied without causing a temperature change is referred to as latent heat. This is the energy required for a substance to change its state (phase) without changing its temperature.
