Study route
5.1. Temperature and internal energy
- The temperature characterizes the body's thermal state, and the internal energy consists of the kinetic energy of the chaotic movement of particles and the potential energy of their interaction.
5.2. Heat transfer
- Energy is spontaneously transferred from a warmer body to a less heated one. Under different conditions, transport results in collision of particles, flow of matter or electromagnetic radiation.
5.3 Heat quantity and balance
- The amount of heat is measured by the energy transferred at the heat transfer, which depends on the mass, temperature change and specific heat intensity of the substance for heating.
