3.2 Gas Behavior Flashcard

Front

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

Back

Pressure is directly proportional to the number of particles in a gas at constant volume and temperature.

Front

What happens to the rib cage during inhalation?

Back

The rib cage lifts up and out.

Front

What occurs to the volume of the chest cavity when exhaling?

Back

The volume of the chest cavity decreases.

Front

What causes an increase in tire pressure?

Back

An increase in tire pressure is caused by more collisions of air particles with the walls of the tire, resulting in increased force.

Front

What remains constant when the number of gas particles increases in a rigid container?

Back

Temperature remains unchanged.

Front

Define gas pressure.

Back

Gas pressure is the force exerted by gas particles colliding with the walls of a container.

Front

What is Boyle's Law?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

Explain Charles's Law.

Back

Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature.

Front

What is the ideal gas law equation?

Back

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

Front

How does temperature affect gas behavior?

Back

As temperature increases, the kinetic energy of gas particles increases, leading to higher pressure if volume is constant.
