Heat Convection in Liquids
Energy is all about action! Thermal energy is transferred in many ways. The thermal energy of a substance can be determined by adding up all the kinetic and potential energy of its molecules. Convection is one form of energy transfer where heat energy is transferred by large scale movement in a gas or liquid. Convection currents form, which are streams of gas or liquid powered by convection. Some of this movement is caused by differences in density. You might remember that density how much matter there is in a given amount of space. In this convection current experiment for kids, you are going to make convection currents in water, which you will be able to observe with the help of food coloring.
How does the convection of water work?
