Gas Laws Review

What does Boyle's Law state?

• The volume of a gas is directly proportional to the temperature of the gas. 
• The volume of a gas is directly proportional to the pressure of a gas. 
• The volume of a gas is inversely proportional to the pressure. 

How do you convert Celsius to Kelvin?

• Add 273
• Subtract 273
• You can't convert those
• They are the same thing

A scientist records 8 moles of gas. The scientist does not check the pressure of this gas. At t later time the scientist measures the volume of gas to be 150 ml and the new number of moles of gas to be 48 what was the orginal volume of the gas

• 25 ml

• 0.39 ml

• 2.56 ml

• 2.5 ml

A scientist records the volume of a gas in bubble to be 0.43L The scientist determines that that the bubble contains 8 moles of oxygen. The scientist checks in on the bubble later to find that the volume has expanded to 129 ml how much oxygen is in the bubble now.

• 2.4 moles

• 3 moles

• 693.38 moles

• 0.001 Moles
