In thermodynamics, heat is the thermal energy transferred between systems due to a temperature difference. [1] . In colloquial use, heat sometimes refers to thermal energy itself. Thermal energy is the kinetic energy of vibrating and colliding atoms in a substance.
e (1) physics : added energy that causes substances to rise in temperature, fuse, evaporate, expand, or undergo any of various other related changes, that flows to a body by contact with or radiation from bodies at higher temperatures, and that can be produced in a body (as by compression) (2)
Mar 6, 2024 · Heat is the thermal energy transfer between systems or bodies due to a temperature difference. Thermal energy, in turn, is the kinetic energy of vibrating and colliding particles. Heat occurs spontaneously from a hotter body to a colder one.
3 days ago · heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder.

Scientists define heat as thermal energy transferred between two systems at different temperatures that come in contact. Heat is written with the symbol q or Q , and it has units of Joules ( J ).
Heat is a form of energy and temperature measures how much energy an object has. The study of heat is really the study of the atoms and molecules that make up an object. The faster the atoms are moving, the hotter the temperature because they have more energy.
a hot condition of the atmosphere or physical environment; hot season or weather: They go up north in the summer to escape the heat. a period of hot weather. a sharp, pungent flavor, as that produced by strong spices.
noun. 1. a. the energy transferred as a result of a difference in temperature. b. the random kinetic energy of the atoms, molecules, or ions in a substance or body. Related adjectives: thermal, calorific. 2. the sensation caused in the body by heat energy; warmth.
