viscosity
a liquid’s resistance to flow
gas
the state in which matter changes in both shape and volume
pressure
amount of force exerted on a given area
Boyle’s Law
for a fixed amount of gas at a constant temperature, the volume of a gas increases as its pressure decreases
Charles’s Law
for a fixed amount of gas at a constant pressure, the volume of the gas increases as its temperature increases
