Unit 12 Gas Laws Review

A student measures the pressure and volume of an empty water bottle to be 1.4 atm and 2.3 L. She then decreases the pressure to 0.65 atm. What is the new volume?

• 2.1 L

• 5.0 L

• 8.2 L

• 3.9 L

How do you convert volume in mL to Liters?

• It doesn't matter, you don't need to

• Multiply by 1,000 (move the decimal 3 places to the right)

• Divide by 1,000 (move the decimal 3 places to the left)
