Section 10-3: Gas Laws

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 ?

  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?

  2. 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?

  3. If 4.58 L a gas is under 754 torr of pressure what happens to the volume is the pressure is increased to 1.10 atm?

  4. 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. Section 10-3: Gas Laws • 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 P1V1 / T1 = P2V2 / T2

  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?
