Heat is transferred between two atoms or molecules in direct contact. The transfer occurs when agitated molecules at high temperatures strike slower molecules at low temperatures, resulting in collisions. Heat transfer occurs through vibrations if the atoms are fixed in a lattice. Conduction takes place in solid, liquid, and gas. For example, when ...
Energy is transferred through a medium like liquid or gas. Molecules carry the energy due to the motion of the fluid. For example, when we boil water in a pan, the molecules at the bottom get heated first and carry the energy to the top. In nature, we experience convection currents due to hot air close to the ground that expands, rises, and cools d...
Energy is transferred without any contact between the atoms or molecules. Energy in the form of electromagnetic radiation is emitted by a heated body and absorbed by another. A medium is not required for energy to travel. Electromagnetic wavescarry thermal energy. For example, Sun emits heat through radiation, and we feel its warmth. Equation The i...
Heat transfer is related to temperature change. Heat is equal to the product of the mass, the change in temperature, and a proportionality constant called the specific heat.
Sep 18, 2022 · Heat transfer is the movement of heat due to a temperature difference between a system and its surroundings. The energy transfer is always from higher temperature to lower temperature, due to the second law of thermodynamics. The units of heat transfer are the joule (J), calorie (cal), and kilocalorie (kcal).
