Write the SI unit of heat capacity.

Explanation

To find the SI unit of heat capacity, we can follow these steps:

### Step 1: Understand the concept of heat capacity
Heat capacity is defined as the amount of heat energy required to change the temperature of an object by one degree Celsius (or one Kelvin).

### Step 2: Identify the quantities involved
Heat capacity (C) is related to the amount of heat (Q) added or removed and the change in temperature (ΔT). The relationship can be expressed as:
\[ C = \frac{Q}{\Delta T} \]
