When a sample of gas is confined to a smaller volume what happens to the pressure of the gas ?

• It decreass
• It does not change
• It increases

What compression pressure did he use in if first successful engine?

• 400 PSI
• 450 PSI
• 600 PSI

Why did that design fail?

• cylinder heating
• cylinder plunging
• cylinder cooling

How does he temperature change when sample of air is compressed?

• temperature decreases
• temperature increases
• temperature does not change
