EVERYDAY SCIENCE

Detailed explanation-1: -Calorimetry is used to measure amounts of heat transferred to or from a substance.

Detailed explanation-2: -Calorimetry is the process of measuring the amount of heat released or absorbed during a chemical reaction.

Detailed explanation-3: -Chemical thermodynamics deals with the relationship between heat and other forms of chemical energy, kinetics with chemical reaction rates. Subdisciplines of physical chemistry include electrochemistry, photochemistry (see photochemical reaction), surface chemistry, and catalysis.

Detailed explanation-4: -Thermochemistry is a branch of chemistry that qualitatively and quantitatively describes the energy changes that occur during chemical reactions. Energy is the capacity to do work. The first law of thermodynamics states that the energy of the universe is constant.

Detailed explanation-5: -Thermochemistry is the study of the heat energy which is associated with chemical reactions and/or phase changes such as melting and boiling. A reaction may release or absorb energy, and a phase change may do the same.
