Study Notes
Gas Law Calculations
- A gas with a volume of 5.22 L, pressure of 735 torr, and temperature of 23°C is given.
- The pressure is changed to 1.88 atm; calculate the new volume.
- 1 atm = 760 torr = 1.01325 bar = 101325 Pascal
- The new volume is 3.36 L.
Charles' Law
- Calculate the new volume of a gas at a temperature of 165°C, using Charles' Law, given initial volume and temperature.
- The calculation requires the initial volume and temperature and the given new temperature.
Oxygen in a Scuba Tank
- A scuba tank has 0.29 kg of oxygen, compressed into 2.3 L at 9°C.
- Calculate the pressure of the gas inside the tank.
