What is Thermodynamics?
The branch of science dealing with heat, work, energy transformations, and the relationships between properties of matter (temperature, pressure, volume). The four laws of thermodynamics govern energy flow and the spontaneity of processes in chemistry and physics.

The branch of science dealing with heat, work, energy transformations, and the relationships between properties of matter (temperature, pressure, volume). The four laws of thermodynamics govern energy flow and the spontaneity of processes in chemistry and physics.
Thermodynamics guides the design of chemical and engineering processes, predicting energy requirements and efficiency. It underpins the operation of heat engines, refrigerators, and power plants. Chemical thermodynamics determines reaction feasibility, equilibrium constants, and electrode potentials…
Thermodynamic analysis identifies processes with large heat release or high equilibrium pressures that pose safety risks. Entropy and enthalpy changes guide the assessment of thermally unstable or explosive compounds.
The formula or notation for Thermodynamics is: ΔU = q + w; ΔS_universe ≥ 0; G = H - TS
