5.2: The First Law of Thermodynamics. The first law of thermodynamics states that the energy of the universe is constant. The change in the internal energy of a system is the sum of the heat transferred and the work done. At constant pressure, heat flow (q) and internal energy (U) are related to the system's enthalpy (H).

Thermochemistry is a branch of chemistry that studies the heat involved in various reactions. Heat is a form of energy. The energy from heat can drive a chemical reaction, be released from a reaction, or both! Thermochemistry attempts to understand and explain the transformations the energy in a reaction undergoes. "Thermo" means relating ...
