Boyes Charles Combined Gas Laws

A container holds 600 L of air at pressure of 2 atm. If the pressure on the gas is increased to 5 atm, what will its volume become?

• 240 L

• 235 L

• 230 L

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

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

A scuba diver's air tank occupies 4.98 L at 2.6 atm of pressure. What volume does the tank occupy at 1.8 atm pressure?

• 12.9 L

• 0.72 L

• 7.2 L

• 3.44 L

What is the new volume of the gas if the pressure on 350 L of oxygen at 1.5 atm is decreased to 1 atm?

• 420 L

• 350 L

• 525 L

• 285L

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.

• 0.52 L
• 1.56 L
• 0.173 L
• 1.00 L

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

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

3. According to Boyle's law, at constant temperature, as the pressure of a given sample of gas is increased, the volume will –

• Increase
• Decrease
• Remains the same

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

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

• 250 L

• 204 L

• 196 L

• 162 L

The volume of a sample of a gas at 273 ^oC is 200 L. If the volume is decreased to 100 L at constant pressure, what will be the new temperature of the gas?

• 0 K

• 546 K

• 273 K

• 100 K
