Behavior of Gases Test

Front

Why is a gas easier to compress than a liquid or a solid?

Back

The volume of a gas’s particles is small compared to the overall volume of the gas.

Front

What happens to the piston of a sealed syringe when it is plunged into cold water?

Back

The piston slides in.

Front

Which gas effuses the most rapidly?

Back

Hydrogen.

Front

How does gas propellant move in an aerosol can?

Back

From a region of high pressure to a region of lower pressure.

Front

What happens to the pressure of a fixed volume of gas as temperature increases?

Back

The pressure will increase.

Front

Define effusion in the context of gases.

Back

Effusion is the process by which gas particles pass through a tiny opening from one container to another.

Front

What is the relationship between pressure and volume in a gas at constant temperature?

Back

They are inversely related (Boyle's Law).

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Front

What is the significance of the gas constant (R) in the ideal gas law?

Back

It relates the pressure, volume, temperature, and amount of gas in a system.

Front

What happens to gas particles when temperature increases?

Back

They move faster and collide more frequently.
