Thermodynamics Calculators

All thermodynamics calculators in one place.

Calculate heat energy transferred using Q = mcΔT.

Calculate specific heat capacity from mass, heat energy, and temperature change.

Calculate the heat energy required for a phase change.

Calculate the change in length, area, or volume due to a temperature change.

Calculate pressure, volume, temperature, or moles using PV = nRT.

Find gas pressure from PV = nRT, a pressure change, or a partial pressure with Dalton's Law.

Find gas volume from PV = nRT, a volume change, or a new volume with Avogadro's Law.

Find gas temperature from PV = nRT, a pressure/volume change, or Gay-Lussac's Law.

Calculate pressure or volume of a gas at constant temperature.

Calculate volume or temperature of a gas at constant pressure.

Calculate pressure or temperature of a gas at constant volume.

Calculate pressure, volume, or temperature using the combined gas law.

Calculate final volume, final moles, initial volume, or initial moles of a gas using V1/n1 = V2/n2.

Add partial pressures to find total pressure, or solve for a partial pressure, mole fraction, or total pressure.

Calculate effusion or diffusion rate, or molar mass, using Rate1/Rate2 = sqrt(M2/M1).

Calculate the maximum theoretical efficiency of a heat engine.
