What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

A gas at a volume of 4 liters is at a pressure of 8 Pa. The volume is changed to 16 Liters, what must the new pressure be?

• 1 Pa
• 12 Pa
• 10 Pa
• 2 Pa

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

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

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
• 29.16 L
• 4200.0 L
• 291.6 L

In Charles' Law the pressure remains constant.

• True
• False

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

• 250 mL
• 204 mL
• 196 mL
• 160 mL

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 

5 atm = ________ kPa

• 506.5 kPa
• 505 kPa
• 456 kPa
• 598 kPa

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂

A gas is heated from 263K to 298K. The volume is increased from 24.0L to 35.0L. If the original pressure was 1.00 atm, what is the new pressure?

• 1.65 atm
• 1.28 atm
• 0.61 atm
