An area of science concerned with amount of heat absorbed or released in physical or chemical change is Thermo chemistry.
Energy is the capacity to supply heat and do work
Potential Energy is the energy possessed by a body because of its relative position, composition of condition
Kinetic Energy is the energy possessed because of its motion.
According to kinetic theory of gases,heat is the kinetic energy possessed with the random motion of atoms and molecules
Temperature is the quantitative measure of hot or cold.
Thermal energy is the transfer of energy between two bodies at different temperatures
Enthalpy = U+PV and dH= CpdT
The process of measuring the heat in a physical or chemical change is calorimetry
Internal energy is the sum of all forms of energy present in a substance
State Function is the property depending only the state of the system and independent of the path followed
