Question

Name the branch of Science which explains heat energy

Answer 1

Heat energy:

1. Heat energy is the outcome of the continuous movement of atoms, molecules or ions in solids, liquids and gases.
2. It can be transferred from one object to another object.
3. The transfer or flow rate due to the difference in temperature between the two objects is called heat.
4. It is a form of energy, and therefore the SI unit of heat is also joules (J).
5. One joule is defined as the amount of energy needed to raise the temperature of a given mass by one degree.

Branch of Science:

1. Thermodynamics is a branch of physics (or science) that deals with the equilibrium, energy and its transformation from one form to another.
2. It deals with the relations between heat and work and the properties of the system, which are in equilibrium.
3. Thermodynamics is a science that studies various interactions amongst energy, heat, work, and temperature, with matter that brings about significant changes in the macroscopic properties of a substance that are measurable.

Thus, thermodynamics is the branch of science that explains heat energy.
