Boyles Law Calculations

The relationship of which two variables are compared in Boyle's Law?

• pressure & volume
• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

Which two variables must be held constant for Boyle’s Law to apply?

• pressure & volume
• volume & temperature
• temperature & moles (amount of gas)
• volume & moles (amount of gas)

Pressure and volume have a(n) _________ proportionality.

• direct
• inverse
• linear
• exponential

Lebron James 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 Lebron’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 is the correct equation for Boyle's Law?

• P₁/T₁ = P₂/T₂
• P₁/V₁ = P₂/V₂
• P₁ • T₁ = P₂ • T₂
• P₁ • V₁ = P₂ • V₂

Taylor Swift 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. Ms. Swift 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.

For the problem below, what is the value for the final pressure?

A gas with a volume of 4.0 L at 90.0 kPa expands until the pressure drops to 20.0 kPa. What is its new pressure if the temperature doesn’t change?

• 4.0 L

• 20.0 kPa

• 90.0 kPa

• 18.0 L

On the sidelines at the game, a container filled with oxygen for the players has a volume of 0.03 L and a pressure of 4.00 atm. If the pressure of the oxygen gas is reduced to 2.71 atm and the temperature is kept constant, what is the new volume of the oxygen gas?

• 0.32 L
• 361 L
• 0.9 L
• 0.04 L

The volume air in the lungs of an average NFL player is 2.4 L and the pressure is 101.70 kPa during exhalation. If the pressure during inhalation is 101.01 kPa, what is the volume of the lungs of a NFL player during inhalation?

• 2.38 L

• 2.4 L

• 5.1 L

• 4284 L

For a teammate’s birthday party, Sabina needs to buy a helium tank to fill up all of the balloons. If the helium must be compressed from an original volume of 27.0 L at 14.7 psi, down to a volume of 3.00 L, what would be the final pressure of the helium?

• 132.3 psi

• 1.63 psi

• 5.51 psi

• 132.3 L
