Write the expression for the heat energy Q received by m kg of a substance of specific heat capacity c J `kg^(-1)K^(-1)`when it is heated through `Deltat^@`C.

Explanation

To derive the expression for the heat energy \( Q \) received by a substance when it is heated, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Specific Heat Capacity**:
The specific heat capacity \( c \) of a substance is defined as the amount of heat required to raise the temperature of 1 kg of that substance by 1 degree Celsius (or 1 Kelvin).

2. **Identifying Variables**:
...
