Gay-Lussac's Law Revision

A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0 °C is placed inside an oven whose temperature is 50.0 °C. The pressure inside the container at 20.0 °C was at 3.00 atm. What is the pressure of the nitrogen after its temperature is increased to 50.0 °C?

• 3.31 atm

• 5.34 atm

• 9.05 atm

• 6.83 atm

A gas has a pressure of 699.0 mmHg at 40.0 °C. What is the temperature at standard pressure? (Note Standard pressure = 1 atm or 760 mmHg)

• 120 K

• 340 K

• 356 K

• 87 K

What happens to the pressure of a closed gaseous system when the temperature increases two-fold?

• The pressure is halved

• The pressure stays the name

• The pressure is quadrupled

• The pressure is doubled

The graph depicted here represents which of the gas laws?

• Newton's second law

• Charles's law

• Boyle's law

• Gay-Lussac's law

If the temperature of a gas increases, what happens to the pressure?

• We must know the molecular formula of the gas to determine the relationship

• Pressure will decrease

• Pressure will increase

• Pressure will remain unchanged

What is kept constant in Gay-lussac's law?

• moles of gas

• pressure

• moles of gas + temperature

• moles of gas + volume
