Which of the following would increase the (gas) pressure of a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume
• All of these

What about gases can be measured?

• Pressure and Volume
• Temperature, Volume, and Pressure
• Volume and Temperature
• Pressure, Temperature, Volume, and Moles

Pressure is

• defined as the mass that an object exerts when at rest.

• not a measurable in gases.

• defined as the number of moles of substance divided by the mass of the substance.

• created by the force of the gas particles impacting the walls of the container.

Absolute zero is

• 0 K

• where there is no molecular movement

• the coldest temperature possible

• all of these
