Question

1. Zion Williamson* has taken up free diving as a way to keep in shape and pass the time while he is quarantined. At the surface of the ocean (recall that pressure is 1 atm at sea level) Zion takes a deep breath and fills his lungs with 7.00 Liters of air. What volume (in L) will the air in his lungs occupy when he dives to a depth where the pressure is 1.92 atm?

Calculate the volume in liters (L) to three significant figures. However, do not include units when inputting your answer.

*Disclaimer - I have no idea how Zion passed the time while quarantined. However, I am excited that the NBA begins again this week :)

2.

A NBA basketball has a volume of 7112 cm³. The air inside the basketball exhibits a pressure of 1.565 atm. If the temperature on the basketball court is 21.1 degrees Celsius, how many moles of air are inside the basketball? (Assume that the air inside the basketball behaves like an ideal gas.)

3.

Nitro brew coffee is a cold brew coffee that is infused with nitrogen gas. This gives the cold coffee a creamy taste. A 322 mL can of nitro brew is under 3.15 atm of pressure and is being stored in a refrigerator at 4.5 degrees Celsius. The nitrogen gas in the can occupies the entire volume even though there is liquid in the can as well. When the can is opened, the pressure decreases to 1.00 atm. If the open can is left out and warms to a temperature of 15.0 degrees Celsius, what volume, in Liters, does the nitrogen gas now occupy? (Assume that the nitrogen gas behaves like an ideal gas.)
