1.At 17.0C, a sample of helium gas stored in a metal cylinder exerts a pressure of 14.70 atm. What will the pressure become if the tank is placed in a closed room where the temperature changes to 19.2 C?

2.The total pressure of 2 gases (gases A & B are mixed in a tank) is 265.6 kPa. If gas A exerts 83.58 %, what pressure does gas B exert in the tank?

3.A gas at 1660.1 kPa pressure occupies 19.80 L at 33.2 C. What will be its new volume (in L) if the temperature was changed to 10.9 C and the pressure to 3620.1 kPa?
