FLUID such as gases & liquids.Type of convection: Natural convectionForced convection Natural convection:When convection takes place due to buoyant force there is a difference in densities caused by the difference in temperature it is KNOWN as natural convection.Forced Convection: An external source such as fans & pumps is used for creating induced convection, known as forced convection.One of the common examples of natural convection is Land & sea breeze. This phenomenon occurs during the day as land gets warmer quickly than the sea, the temp above the land rises and heats the surrounding air.Warm air is less dense, it expands and starts rising to create a low-pressure area over the land meanwhile there is RELATIVELY high pressure over the sea.The difference in pressure causes the air to flow from sea to land known as the Sea Breeze and Vice-versa in the NIGHT is known as Land breeze. AcclimatizationIt is the process in which an individual organism adjusts to a change in its environment, allowing it to maintain performance across a range of environmental conditions.RadiationIt is the emission or transmission of energy that travels in the FORM of waves or particles through a material medium.ConductionHeat transfer through matter by molecular activity is known as conduction.
