Question

Describe the movement of heat between two substances of different temperatures

Answer 1

Form of energy that is transferred between two substances at different temperatures. The total energy in a substance, due to the movement of atoms (kinetic energy). The hotter the object more kinetic energy. The movement of thermal energy from one thing to another thing of different temperature, hot to cold.

Answer 2

The movement of heat between two bodies is produced by three methods: conduction, convection, and radiation.

Step-by-step explanation:

Conduction is the process of heat transfer due to the collision of some molecules with others, it is observed that the particles with more energy deliver energy to the less energetic, thus producing a flow of heat from the highest temperature to more low.

Convection is the mechanism of heat transfer by mass movement or circulation within the substance. If there is a temperature difference inside a liquid or gas, a movement of the fluid will almost certainly occur. This movement transfers heat from one part of the fluid to another.

Convection transfers heat through the exchange of hot and cold molecules, for example, the water in a kettle gets hot even though only its bottom is in contact with the heat source.

Thermal radiation is the energy emitted by matter that is at a known temperature, produced from the source outwards in all directions
