Mr. Fox 8th Grade Science Class Behavior of Gases Mr. Fox 8th Grade Science Class

Measuring Gases Volume – how much the space of the container that gas is in. Temperature – usually in Celsius or Kelvin Pressure – the force of its outward push divided by the area of the walls of the container. When you fill your bike tires… Pounds per Square Inch (PSI).

Robert Boyle English Scientist 1600s Experimented with volume and pressure because he was trying to improve Air Pumps. Related Pressure and Volume

Boyle’s Law When pressure of a gas increases the volume decreases. When the pressure of gas decreases the volume increases.

Boyle’s Law

Temp and pressure When temp. increases its pressure increases. When temp. decreases its pressure decreases.

Jacques Charles French Scientist late 1700s Examined the relationship between temp. and volume at a constant pressure.

Charles’s Law When temp. of a gas increases, its volume increases When temp. of a gas decreases, its volume decreases

Charles’s Law
