Convection. Liquids and gases are fluids. The particles in these fluids can move from place to place. 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. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
Convection is the transfer of heat through the movement of a fluid, such as water or air. This type of heat transfer can occur in liquids and gases because they move freely, making it possible to set up warm or cold currents. Convection occurs naturally in the atmosphere on a warm, sunny day.he sun's energy moves through space, then through the earth's atmosphere and finally reaches the earth's surface. The sun's radiation warms the earth's atmosphere and surface and becomes heat energy. This heat energy is transferred through the atmosphere by one of three mechanisms:
