the letter of each correct answer on the line.
Column B
Column A
A Boyle's law
1. Relates pressure and volume of a gas.
B Charles's law
2. Relates pressure, volume, and temperature of a gas.
This law can be used in place of all others.
C combined gas law
3. Relates volume and temperature of a gas.
D Gay-Lussac's law
4. Relates pressure and temperature of a gas.
Directions Write the answer to each question.
5. A gas sample at 45°C has a pressure of 123 kPa. If the gas is
cooled to 30°C, what is the new pressure?
6. A 3.4-L sample of a gas has a pressure of 1.9 atm. What is the
new volume if the pressure is increased to 3.5 atm?
7. A gas sample at 20°C has a volume of 1.0 L. What would the
new volume be if the gas is cooled to -15°C?
8. A 732-mL gas sample has a pressure of 540.0 mm Hg. What is
the new pressure if the volume is increased to 1.0 L?
9. What gas law explains why the tires on a car lose pressure in
winter?
10. A reaction occurs in a closed container that produces a gas.
Adding more gas increases the pressure inside the container.
Explain why. What else increases and why?

5)
Gay-Lussac's Law states that the pressure of a given mass of gas varies directly with absolutely the temperature of the gas, once the degree is unbroken constant. law of volumes is extremely just like Gay-Lussac's law, with the sole distinction being the sort of instrumentality. Whereas the instrumentality in a very Gay-Lussac's law experiment is versatile, it's rigid in a very law of volumes experiment.
