Overview

Thermodynamics is the branch of physics that deals with heat, work, and internal energy in systems. It explains how energy is transferred between objects due to temperature differences and how this energy can be converted into useful work. The chapter introduces fundamental concepts such as temperat

Key Concepts

Heat is the form of energy

Heat is the form of energy transferred between systems due to a temperature difference. Temperature is a measure of the average kinetic energy of mole

Processes like isothermal (constant temperature)

Processes like isothermal (constant temperature), adiabatic (no heat exchange), isobaric (constant pressure), and isochoric (constant volume) describe

It states that the change

It states that the change in internal energy of a system (ΔU) equals the heat added to the system (ΔQ) minus the work done by the system (ΔW): ΔU = ΔQ

The Carnor cycle consists of two

The Carnor cycle consists of two isothermal and two adiabatic processes. Its efficiency is given by η = 1 − (T₂/T₁), where T₁ and T₂ are the source an
