EQA02 - Gasses

Front

What is the relationship between gas pressure and the number of particles in a container?

Back

Gas pressure is directly proportional to the number of particles in a container.

Front

What does the kinetic-molecular theory state about the average kinetic energy of gas particles?

Back

The average kinetic energy of gas particles depends only on the temperature.

Front

What happens to the volume of a gas when pressure is increased?

Back

Increasing the pressure on a gas decreases its volume.

Front

What is a key postulate of the kinetic-molecular theory regarding particle collisions?

Back

All collisions between gas particles are perfectly elastic.

Front

What is the effect of increasing the average kinetic energy of gas particles in a balloon?

Back

It results in higher gas pressure inside the balloon.

Front

Define compressibility in the context of gases.

Back

Compressibility is the ability of a gas to decrease in volume under pressure.

Front

What is the relationship between volume and temperature in gases?

Back

Volume and temperature are directly proportional in gases.

Front

What is the significance of the empty space in a gas according to the kinetic-molecular theory?

Back

Most of the volume of a gas is empty space.

Front

How does temperature affect the pressure of a gas?

Back

Increasing the temperature of a gas increases its pressure.

Front

What is an example of the kinetic-molecular theory not holding true for gases?

Back

The attraction between particles causes a gas to condense at low temperatures.
