Thermodynamics Theory

Thermodynamics

Thermodynamics can be represented as thermal + dynamics which mean heat and motion.

Define: it is a branch of science which deals with various forms of energy and tells about following things:

1. Extent of reaction

2. Reactions feasibility

3. Can tell about initial and final state of the system.

4. Can tell about the various properties like temperature, pressure and volume.

Some basic terms related to thermodynamics

System And Surroundings:

A part of the universe which is under investigation termed as system and the universe excluding system is termed as surroundings.

Types of System

A system which can exchange matter as well as energy.

Closed system:

A system which can exchange matter energy but not matter.

Isolated system:

A system which can neither exchange matter nor energy.

Thermodynamic Equilibrium: When pressure and temperature does not change w.r.t time and said to be attained equilibrium.

Thermodynamic Process:

1. Isothermal: It is a process in which temperature constant.

2. Isobaric: It’s a process in which pressure remains constant.

3. Isochoric: It’s a process in which volume remains constant.

4.Adiabatic: q=0
