AP CHEM The Ideal Gas

Front

What is the kinetic molecular theory?

Back

A theory that explains the behavior of gases in terms of particles in constant motion, emphasizing that gas particles are far apart, move randomly, and have negligible attractive forces.

Front

What is an ideal gas?

Back

A hypothetical gas that perfectly follows the kinetic molecular theory, with no intermolecular forces and occupying no volume.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

The temperature of a gas is directly proportional to the average kinetic energy of its particles.

Front

What happens to gas particles at higher temperatures?

Back

Gas particles move faster and have higher kinetic energy.

Front

What is the significance of 1 atm in terms of pressure?

Back

1 atm is a standard unit of pressure equal to 760 mm Hg, 760 torr, or 101,325 Pa.

Front

What is the difference between real gases and ideal gases?

Back

Real gases deviate from ideal behavior due to intermolecular forces and particle volume, while ideal gases follow the kinetic molecular theory perfectly.

Front

What is the behavior of gas particles in a closed container?

Back

Gas particles move freely and collide with each other and the walls of the container, resulting in pressure.

Front

What is the effect of volume on gas pressure?

Back

According to Boyle's Law, if the volume of a gas decreases, the pressure increases, provided the temperature remains constant.

Front

What is Avogadro's Law?

Back

Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain an equal number of particles.

Front

What is the ideal gas law equation?

Back

The ideal gas law is represented 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.
