Problem #1: 600.0 mL of air is at 20.0 C. What is the volume at 60.0C? Problem #2: A gas occupies 900.0 mL at a temperature of 27.0 C. What is the volume at 132.0 C Problem #3: What change in volume results if 60.0 mL of gas is cooled from 33.0 C to 5.00 C? A balloon with a volume of 2.0 L is filled with a gas at 3 atmospheres. If the pressure is reduced to 0.5 atmospheres without a change in temperature, what would be the volume of the balloon? Calculate the decrease in temperature (in Celsius) when 2.00 L at 21.0 C is compressed to 1.00 L. (2.00 L) / 294.0 K) =(1.00 L)/(x)cross multiply to get: 2x = 293 x= 147.0 K Converting 147.0 K to Celsius, we find -126.0 C, for a total a decrease of 147.0 C, from 21.0 C to -126.0 C
