The heat capacity of a system is defined as:
1. The heat required to raise the temperature of the system by 1 degree Celsius.
2. The heat released when the system undergoes a chemical reaction.
3. The heat absorbed when the system undergoes a chemical reaction.
4. The heat required to raise the temperature of the system by 1 Kelvin.
