1. Starting the solid phase, and going to the gas phase, draw and explain the heating curve for water.

2. A helium balloon is released into the air. Use gas laws to predict what will happen to the balloon as it rises higher into the air.

3. What is the volume, in liters, occupied by 0.485 moles of Oxygen gas at 23.0 C and 0.980 atm?

3. What is the volume, in liters, occupied by 0.485 moles of Oxygen gas at 23.0 C and 0.980 atm?

convert the temperature to K and use the formula

P V = n RT  ==>  V = nRT/P =( 0.485 moles 0.082 atm L /molK (273+23)K) / 0.980 atm = ????
