How can we increase the gas pressure inside a sealed container?

• Increase the number of particles inside the container
• Increase the temperature
• Decrease the volume of the container
• All of these

What is the equation used to calculate pressure?

• pressure= force/mass
• pressure =mass/volume
• pressure=area/force
• pressure=force/area

Atmospheric pressure increases as you move towards lower elevations and decreases as you move into higher elevations.

• True
• False

When you increase your depth under water, the water pressure on your body

• increases

• decreases

• stays the same
