2. 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).

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

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

5. Boyle’s Law

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

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