Read each question carefully and answer to the best of your ability. Show all your work for calculation problems. Use the formula: P₁V₁/T₁ = P₂V₂/T₂. Remember that temperature must be in Kelvin.
1. What three properties of a gas are related by the Combined Gas Law?
2. Explain how Boyle's Law, Charles's Law, and Gay-Lussac's Law are all incorporated into the Combined Gas Law.
1. To use the Combined Gas Law, temperature must always be expressed in .
2. If the pressure and temperature of a gas remain constant, the volume will also .
3. The Combined Gas Law is derived from the ideal gas law when the number of moles of gas is held .
1. A gas occupies 10.0 L at 2.00 atm and 273 K. What will be its new volume if the pressure increases to 4.00 atm and the temperature increases to 300 K?
5.49 L
10.0 L
21.9 L
27.3 L
2. If a gas initially at 1.5 atm, 2.0 L, and 298 K is compressed to 1.0 L and its temperature is raised to 350 K, what is the new pressure?
1.27 atm
3.52 atm
2.14 atm
4.00 atm
1. A balloon contains 5.0 L of air at 1.0 atm and 25°C. If the balloon is taken to a location where the pressure is 0.85 atm and the temperature is -10°C, what will be the new volume of the air in the balloon?
2. A gas has a volume of 120 mL at 2.0 atm and 300 K. If the volume changes to 150 mL and the pressure changes to 1.5 atm, what is the new temperature of the gas in Celsius?
