Whenever you heat up or cool down an object, there is a CHANGE IN ENERGY.
The amount of energy STORED or RELEASED from a system as its temperature changes can be calculated by knowing the SPECIFIC HEAT CAPACITY.
Different materials need different amounts of energy to change their temperature.
The SPECIFIC HEAT CAPACITY (SHC) is a property that tells us how much heat energy (in joules) is needed to raise the temperature of 1 kilogram of a substance by 1 degree Celsius (°C).
It's a property of a material that tells you how easy it is to HEAT UP or COOL DOWN.
Here's a simple way to understand it:
To calculate the change in thermal energy of a system, you can use the formula:
