SCIENCE 10 - MODULE 4.1

What is the formula for Boyle's Law?

• P1V1=P2V2

• P1V2=P2V1

• P1V1/P2V2

• P1/V1=P2/V2

What is the new volume of the gas if the pressure on 350 L of oxygen at 720 mm Hg is decreased to 600 mm Hg?

• 420 L

• 4200.0 L

• 29.16 L

• 291.6 L

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure?

• 12.9 L

• 7.2 L

• 0.72 L

• 3.44 L

A gas at a volume of 4 liters is at a pressure of 2 atm. The volume is changed to 16 Liters, what must the new pressure be?

• 2 atm

• 10 atm

• 12 atm

• 0.5 atm

The pressure on a sample of gas is increased from 1.0 atm to 3.0 atm. If the new volume is 0.52 L, find the original volume.

Tom Brady enjoys balloon animals from the carnival. He just received a balloon giraffe that has an initial temperature of 39.0°C and a volume of 1.28 L. If Gronkowski plays a trick on Tom, and puts his balloon giraffe into the freezer, what would be the new volume of the balloon if the temperature drops down to 8.0°C?

• 1.42 L

• 3.78 L

• 6.85 x 10.34 L

• 1.15 L

Tom wants his balloon back to normal size so he decides to put it on a heating vent. If the balloon initially has a volume of 0.6 L and a temperature of 293 K, what will the volume of the balloon be when it heats up to a temperature of 176°C?

• 0.39 L

• 0.78 L

• 0.92 L

• 0. 92 K

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be?
