Explanation:
Convection is the process of carrying heat stored in a particle of the fluid into another location. Heat loss may occur by convection to cooler surrounding air or heat gain from surrounding warmer air.
A convection current is a process which involves the movement of energy from one place to another. Convection currents tend to move a fluid or gas particles from one place to another. These are created as a result of the differences occurring within the densities and temperature of a specific gas or a fluid.
Everyday Examples of Convection
radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting - Ice melts because heat moves to the ice from the air.
