What is definition of heat? And why it's unit is kgm^2/s^2?
I couldn't be able to link the unit to the definition.

Heat is a form of energy that is transferred from one object to another due to a difference in temperature. It can also be defined as the total kinetic energy of all the particles in a substance.
The unit of measurement for heat is Joules (J). However, in some cases, calories (cal) or British Thermal Units (BTUs) may also be used.
Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the total kinetic energy of all the particles in a substance. In other words, temperature measures the intensity of heat, while heat is the actual energy being transferred.
The three modes of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
Heat can cause changes in the physical properties of a substance, such as expansion or contraction, changes in state (solid, liquid, gas), and changes in color or texture. It can also affect the rate of chemical reactions and can be used for various purposes, such as cooking and heating.
