Front

What is Boyle’s Law?

Back

Boyle’s Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. (P1V1 = P2V2)

Front

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

Back

Increasing pressure on a gas typically increases its temperature, as the particles are forced closer together, increasing their kinetic energy.

Front

What is Charles’ Law?

Back

Charles’ Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant.

Front

What is the process of distillation?

Back

Distillation is a separation technique that involves boiling a liquid to produce vapor and then cooling the vapor to obtain the liquid, effectively separating components based on their boiling points.

Front

What is an intensive property?

Back

An intensive property is a property that does not depend on the amount of substance present, such as boiling point, density, and color.

Front

What is an extensive property?

Back

An extensive property is a property that depends on the amount of substance present, such as mass, volume, and total energy.

Front

What is the kinetic theory of gases?

Back

The kinetic theory of gases explains that gas consists of particles in constant random motion, and the temperature of the gas is a measure of the average kinetic energy of its particles.

Front

What is the relationship between temperature and volume in Charles’ Law?

Back

In Charles’ Law, as the temperature of a gas increases, its volume also increases, provided the pressure remains constant.

Front

What is the boiling point of a substance?

Back

The boiling point is the temperature at which a liquid's vapor pressure equals the external pressure surrounding the liquid, causing it to change into vapor.

Front

What is the significance of the boiling point in physical chemistry?

Back

The boiling point is significant as it helps identify substances and is crucial in processes like distillation and purification.
