Physics- Thermodynamics

Definitions for thermodynamics.

First Law of Thermodynamics

The internal energy of a system is increased by heating or work done on the system

Boyle’s Law

Pressure of a gas is inversely proportional to the volume that it occupies, at a constant temperature and for a fixed mass of gas

Charles’ Law

Volume of a gas is proportional to its absolute temperature, at a constant pressure and for a fixed mass of gas

Pressure Law

Pressure of a gas is proportional to its absolute temperature, at a constant volume and for a fixed mass of gas

Work done by a gas

At constant pressure, if gas expands, work is done against it’s surroundings, if a gas is compressed, work is done to it

Ideal Gas Laws

• Random Motion

• No attraction between particles

• Volume of molecules is negligible

• Elastic Collisions

• Duration of collision is negligible

Specific Heat Capacity

Energy required to raise the temperature of a 1Kg of a substance by 1 degrees

Specific Latent Heat

Energy required for 1Kg of a substance, without change in temperature to change state
