How do you convert from K to °C?

K = C° + 273.15

What could happen to a water heater if the valve system malfunctions?

It could burst

100

What has to remain constant in Gay-Lussac's law?

Volume

200
How did Gay-Lussac study the properties of gases?

By gathering measurements and collecting samples in hydrogen-filled balloons

200

What is 40°C in K?

313.15 K

Why does a pressure gauge for a propane tank register a lower pressure when it's cold?

The molecules don't have as much kinetic energy, so they hit the walls of the tank with less force

200

What is another name for Gay-Lussac's law

The law of combining volumes

300

Which revolution(s) did Gay-Lussac live through?

The French and chemical revolutions

300

What is 225 K in °C?

-48.15°C

300

How does a pressure cooker increase the boiling point of water?

As the water heats up, water vapour molecules collide with the walls with more force, increasing the pressure. Since pressure and temperature are directly proportional to each other, the boiling point increases

300

What is the main idea of Gay-Lussac's law?

When the mass and volume of an ideal gas remain constant, the pressure exerted is directly proportional to its absolute temperature

400

What school was Gay-Lussac chosen to attend?

École Polytechnique

400

The pressure of a gas in a cylinder is 6 atm at 27°C. What would the final pressure of the gas be if it was heated to 77°C?

Pf = 7 atm

400

What is on the warning label of an aerosol can and why is it there?

It says to keep it away from heat. When an aerosol can is exposed to high temperatures, the pressure inside the can increases and it can explode

400

Name 3 ideal gases

Hydrogen, helium, nitrogen, oxygen

500

In which year(s) did Gay-Lussac come to the conclusion that gases expand as temperature increases?

1801-1802

500

The pressure inside a scuba tank after it cools from 340.0 K to 22.0°C is 203 atm. Calculate the initial pressure.

Pi = 234 atm

500

What are two causes of an air pressure increase in tires?

Friction, high temperatures

500

What is the difference between Gay-Lussac's law and Charles's law?

The container is rigid in Gay-Lussac's law and flexible in Charles's law
