Therm energy transfer answers
1. Conduction: This is the transfer of heat energy through direct contact between two objects or substances. For example, when you place a metal spoon in a hot cup of tea, heat energy is transferred from the hot tea to the spoon through conduction.
2. Convection: This is the transfer of heat energy through the movement of fluids (liquids or gases). For example, when you heat a pot of water on a stove, the heat energy is transferred from the burner to the water through convection.
3. Radiation: This is the transfer of heat energy through electromagnetic waves. It does not require any medium to transfer heat and can occur in a vacuum. for example, the sun radiates heat energy to the Earth through radiation.
4. Therm energy transfer calls are efficiency, which refers to the amount of useful energy transferred or converted compared to the total energy input. A high efficiency means a larger proportion of the input energy is converted into useful work or heat, while a low efficiency means a smaller proportion is converted into useful energy.
5. Heat transfer can also be influenced by factors such as the surface area, temperature difference, and the thermal conductivity of the materials involved.
