How does convection transfer energy?

Heat transfer by conduction and convection. Heat is thermal energy. It can be transferred from one place to another by conduction, convection and radiation. Conduction and convection involve particles, but radiation involves electromagnetic waves. read more

Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. read more

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. read more

Convection is the transfer of thermal energy through movement of particles from one location to another. Usually occur in fluids (liquids and gases) Example with boiling water: Water at bottom of pan is heated first. Heated water expands and density decreases. read more
