Gas

When heat is added to a sample of gas sealed in a container, which of the following will most likely happen?

• The temperature of gas will increase because the gas molecules will move much more slowly.
• The temperature of gas will decrease because the gas molecules will move faster
• The temperature of gas will increase because the gas molecules will move faster. 
• Temperature of gas will decrease because the gas molecules will stop moving

As pressure goes up, volume 

• goes down.
• goes up.
• stays the same

The formula for pressure

• Pressure = Force divided by Area

• Pressure = Force times Area

• Pressure = Area divided by Force

• Pressure = Area times Force

When you increase your altitude, the atmospheric pressure

• increases

• decreases

• stays the same
