Chemistry 102 Summative Review

Front

What happens to the volume of a gas when the temperature decreases?

Back

The volume of a gas decreases when the temperature decreases, according to Charles's Law.

Front

What is the definition of a solvent in a homogeneous mixture?

Back

A solvent is the substance in a solution that dissolves the solute, typically present in the greater amount.

Front

How do you calculate the new temperature of a gas when its volume changes?

Back

Use the formula: (V1/T1) = (V2/T2), where V is volume and T is temperature in Kelvin.

Front

What does the unit 'atm' measure?

Back

The unit atmosphere (atm) measures pressure.

Front

What units are commonly used to measure mass?

Back

The mass of an object is commonly measured in grams (g).

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature in Kelvin, provided the pressure remains constant.

Front

What is the relationship between pressure and volume in gases?

Back

According to Boyle's Law, the pressure of a gas is inversely proportional to its volume when temperature is held constant.

Front

What is the definition of a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the composition is uniform throughout.

Front

What is the formula for calculating pressure?

Back

Pressure (P) can be calculated using the formula: P = F/A, where F is force and A is area.

Front

What is the significance of the Kelvin scale in chemistry?

Back

The Kelvin scale is significant in chemistry because it is an absolute temperature scale used in gas law calculations.
