Gas laws

constant volume pressure

At ________ is inversely proportional to the temperature.

Liquids

________: increase in temperature equals increase in volume.

constant temperature

At ________ the pressure is inversely proportional to the volume.

constant pressure

At ________ the volume is directly proportional to the temperature.

straight line

They move in a(n) ________ but if they experience an elastic collision they can be steered off and accelerate or decelerate.

substance

Open system: ________, matter and energy is exchanged with the environment.

thermodynamic system

A(n) ________ is a system where particles are in ceaseless interaction with each other.

Example

blood, human body etc

• Open system

substance, matter and energy is exchanged with the environment

• Closed system

substance and matter are not exiting but energy can move in or out of the system

• Isolated system

no matter or energy goes in or out of the system

Extensive variable

if a system is made of subsystems its change is proportional to each subsystems size

Intrinsic variables

if a system is made of subsystems it doesnt change

pV/T = constant
