SET 3

Front

What causes pressure in a gaseous system?

Back

Pressure arises from the incessant collisions of moving particles with the boundaries of their container.

Front

According to kinetic theory, what do gas particles possess?

Back

Gas particles possess mass and velocity.

Front

How is pressure defined mathematically?

Back

Pressure (P) is defined as P = F/A, where F is force and A is area.

Front

What happens to pressure when the average kinetic energy of gas particles increases?

Back

As the average kinetic energy increases, the speed and collision frequency of particles rise, elevating pressure if the volume remains constant.

Front

What effect does compressing a gas at constant temperature have on pressure?

Back

Compressing a gas reduces its volume, forcing particles into a smaller space, which increases the collision rate and pressure.

Front

What fundamental relationship is essential for describing gas behavior?

Back

The relationship between microscopic particle motions and macroscopic pressure is essential for describing gas behavior.

Front

What real-world applications are based on the principles of gas behavior and pressure?

Back

Real-world applications include pressure cookers and pneumatic devices.

Front

How do gases respond to changes in temperature, volume, or particle number?

Back

The link between microscopic motions and macroscopic pressure facilitates predictions about gas responses to changes in temperature, volume, or particle number.
