What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase
• Decrease
• Nothing
• Explosion!

Which container will have lower pressure?

• left
• right
• they both have the same pressure

If the temperature of a gas increase and volume is held constant, the pressure exerted by the gas on the walls of its container

• Decreases
• Increases
• Does not change

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

Why does a car get low tire pressure in the COLD...what two variables are to blame? 

• Pressure and Temperature
• Temperature and Volume
• Volume and Pressure
• Temperature and Weight 

Michael Floyd is learning to calculate using the equation for Boyle’s Law. The problem states that the volume of a gas increased from 1.0 L to 3.3 L and the initial pressure was 1.5 atm while temperature was held constant. Michael calculated the problem and got the answer of 2.3 atm for the final pressure. Does this answer make sense? Why or why not?

• Yes, if volume increases then so does pressure.
• Yes, if volume decreases then pressure increases.
• No, if volume increases then pressure should decrease.
• No, if volume decreases then pressure should also decrease.

How are Volume and Temperature related?

• Inversely
• Directly
• Indirectly
• Constant

LeGarrette Blount decides to go scuba diving while on vacation in Mexico. As he swims deeper into the ocean, the pressure pushing on him increases. Based on the relationship in Boyle’s law, what would happen to the volume of a LeGarrette’s lungs with this increase in pressure?

• volume of the lungs would increase
• volume of the lungs would have no change
• volume of the lungs would double
• volume of the lungs would decrease

What type of relationship do pressure and volume have?

• direct
• inverse
• they are unrelated
• symbiotic
