An increase in a body of water's temperature caused by adding warmer water is called a. thermal pollution c. convection b. specific heat d. thermal warming

d.

thermal warming warmer by more heat

The correct answer is (C) Convection

We know that heat energy is transferred from hot places to cooler places by a process called convection. Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. In the given case, there is warm water and when that warm water is added to cold water the energy from hot water adds to the cold water resulting an increase in the temperature of colder water. So option C is the correct answer.
