Quiz on Gas Laws and Properties

Which of the following is a characteristic of gases?

• They have a definite shape and volume.

• They have no definite shape but have a definite volume.

• They have no definite shape and no definite volume.

• They have a fixed arrangement of molecules.

Which scientist discovered the inverse relationship between gas pressure and volume?

• Jacques Charles

• Robert Boyle

• Lord Kelvin

• Evangelista Torricelli

Boyle's Law states that pressure and volume of a gas are:

• Directly proportional

• Inversely proportional

• Unrelated

• Both increase at the same rate

What happens to gas pressure when the volume is reduced at constant temperature?

• It increases

• It decreases

• It stays the same

• It doubles

According to Charles's Law, as temperature increases, the volume of gas will:

• Decrease

• Increase

• Stay the same

• Turn into a liquid

What is the correct formula for converting Celsius to Kelvin?

• K = °C + 273.15

• K = °C - 273.15

• K = 273.15 × °C

• K = 273.15 / °C

What unit is commonly used to measure pressure?

• Kelvin

• Pascal

• Gram

• Liter

The force exerted by air molecules in Earth's atmosphere is known as:

• Kinetic energy

• Atmospheric pressure

• Vapor pressure

• Pascal's force

Who formulated the law that states the direct relationship between gas temperature and volume?

• Jacques Charles

• Robert Boyle

• Lord Kelvin

• Evangelista Torricelli

If a gas at constant pressure expands from 2 L to 4 L, what happens to its temperature?

• It decreases

• It increases

• It remains the same

• It turns into a liquid
