b) Show all your work!
• If a sample of a gas has a volume of 150mL when the pressure is 450 mmHg, what is the volume when the pressure is increased to 750mmHg? (assume that temperature and amount of gas is constant)
• 4.50 L of gas exerts a pressure of 100kPa. What will the new pressure be if the volume is expanded to 7.30L?
(assume that temperature and amount of gas is constant)
• While the temperature and amount of gas stays constant, what would happen to the pressure of a balloon if the volume is decrease by half? Use KMT to justify your answer.
c) Show all your work!
• A sample of gas occupies 250mL at a temperature of 200K. What will the volume become at a temperature of 350K? (Assume pressure stays constant)
• A sample of gas occupies 400mL. The gas sample is heated to 100 degree Celsius and the volume becomes 500 mL. What was the original temperature of the gas in Celsius?
