1
If a gas has a given volume of 1.28 L and temperature of 10.0˚C what is the volume if the temperature is lowered to -10.0˚C? If 4.58 L a gas is under 754 torr of pressure what is the volume if the pressure is increased to 1.10 atm? The initial pressure and temperature of a sample of gas are 15.8 kPa and 289 K. If the temperature is increased to 303 K what is the pressure?

The initial pressure and temperature of a sample of gas are 15.8 kPa and 289 K. If the temperature is increased to 303 K what is the pressure?

5
S ECTION 10-3: G AS L AWS A gas sample often undergoes changes in temperature, pressure, and volume all at the same time. All the gas laws are combined in the combined gas law. PV / T = constant P 1 V 1 / T 1 = P 2 V 2 / T 2

6
Some hydrogen gas is collected over water at 20.0˚ C. The partial pressure of the hydrogen is 742.5 torr. What is the barometric pressure at the time the gas is collected? Helium gas is collected over water at 25˚C. What is the partial pressure of the helium, given the barometric pressure is 750.0 mm Hg?
