Study Notes

Specific Heat Capacity

The amount of heat required to raise the temperature of 1 kg of a substance by 1 Kelvin (K) is called the specific heat capacity.
Different substances have different specific heat capacities.
A substance with a higher specific heat capacity requires more thermal energy to increase its temperature by 1 K compared to a substance with a lower specific heat capacity.

Sea Breeze

Cooler air from above the surface of the water moves towards land.
This movement of cooler air is called a sea breeze.
The sea breeze replaces the hot air that has risen upward.
