• Pressure

• Temperature

• Volume

• Moles

The combined gas law can be used to solve:

• Boyle's Law problems

• Charles'Law problems

• Gay-Lussac's Law problems

• All of the above

Which Gas Law has an inversely proportional relationship?

• Boyle's Law

• Charles' Law

• Gay-Lussac's Law

• Henry's Law

Applying Boyle's law, if a 175mL sample of neon had its pressure changed from 75kPa to 150kPa. What is its new volume?

• 350mL

• 87.5mL

• 150mL

• 1.67mL

Use the combined gas law, Chlorine gas occupies 240mL at 12kPa of pressure. What would the pressure have to change to make it occupy 80mL? Given temperature remains constant.

• 4kPa

• 24kPa

• 3.6kPa

• 36kPa

Using the combined gas law, if the volume of a gas at 155kPa changes from 22L to 10L. What is the new pressure if the temperature remains constant?

• 34.1kPa

• 70.5kPa

• 341kPa

• 1.42kPa

Using the combined gas law, if a sample of nitrogen occupies a volume of 250mL at 25C. What volume will it occupy at 95C? given constant pressure.

• 309mL

• 950mL

• 202mL

• 439mL

If a rigid container had 1000 gas particles in it and you added 2000 gas particles to the container, what would be the pressure of the container now as compared to when in was completely empty of gas particles?

• Twice the pressure

• Three times the pressure

• Four times the pressure

• Half the pressure

The real plastic squid in the bottles sink because:

• The bottle gets compressed

• The water in the bottle gets compressed

• The air in the plastic squid gets compressed

• The squid are well trained by your teacher!

If pressure is held constant when using the combined gas law, Which of the three main laws would it become?

• Boyle's Law

• Charles' Law

• Gay-Lussac's Law

• Ideal gas Law
