The 53 pages that link to First law of thermodynamics, each with the reason it gives.

• ThermodynamicsRelated: It formalizes conservation of energy in thermodynamic transformations.

• Conservation of energyRelated: It expresses energy conservation for systems that exchange heat and work.

• Specific heat capacityRelated: Heat supplied to a sample changes its internal energy, often observed as a temperature rise.

• Heat capacityRelated: It distinguishes heat supplied from the portion that changes a system's internal energy.

• Adiabatic processRelated: With heat transfer set to zero, the first law directly relates internal energy to work.

• Carnot cycleRelated: It relates the cycle's net work to the heat absorbed and rejected.

• JouleRelated: Its energy balance expresses heat and work in the same unit.

• Internal energyRelated: It relates internal-energy changes to heat transfer and work.

• EnergyRelated: It expresses energy conservation for thermodynamic systems.

• Thermal efficiencyRelated: It accounts for how supplied heat is divided between work and energy leaving the system.

• Thermodynamic cycleRelated: It accounts for the balance between net heat and net work over a complete cycle.

• Heat engineRelated: It accounts for the heat input as work output plus rejected heat over a complete cycle.

• Brayton cycleRelated: Energy balances determine the cycle’s heat input, rejected heat, and net work.

• Isothermal processRelated: It determines how heat transfer balances work during an isothermal change.

• Carnot's theoremRelated: Energy accounting links an engine’s heat input, rejected heat, and work output.

• Rudolf ClausiusRelated: Clausius's work combined energy conservation with a separate constraint on which processes can occur.

• ExergyRelated: Exergy analysis supplements energy conservation by tracking energy quality.

• Thermodynamic processRelated: It relates energy transfers to the change between endpoint states.

• Diesel cycleRelated: It provides the energy balance for heat input, rejected heat, and work.

• Isolated systemRelated: In an isolated system, its energy balance has no heat or work transfer terms.

• Reynolds transport theoremRelated: Using energy as the extensive property gives open-system energy balances.

• Thermodynamic efficiencyRelated: Energy balances identify the input, useful output, and losses used to calculate efficiency.

• Caloric theoryRelated: The first law accounts for heat and work as energy transfers rather than caloric quantities.

• Chemical energyRelated: Chemical reactions redistribute energy rather than create or destroy it.

• Perpetual motionRelated: It rules out a machine that produces work without drawing energy from somewhere.

• Perpetual motion machineRelated: A machine producing work without an energy input would violate energy conservation.

• CogenerationRelated: It frames cogeneration as recovering energy flows, not creating extra energy.

• Equilibrium thermodynamicsRelated: It constrains energy changes between equilibrium states without specifying a process's detailed dynamics.

• Clausius theoremRelated: Energy conservation alone does not impose the theorem’s inequality.

• Isentropic processRelated: It relates work and heat to energy changes along an isentropic path.

• Energy conversion efficiencyRelated: It requires accounting for all input energy, including energy that does not become useful output.

• Stirling cycleRelated: It accounts for energy entering, leaving, and being stored across each process.

• Thermodynamic equationsRelated: It constrains equations for energy changes and transfers.
