Which law states that the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions?
boyle’s law
charles’s law
dalton’s law
gay-lussac’s law

Charles law

Explanation:

Relationship between volume and absolute temperature is given by Charles's law.

According to Charles's law, at constant pressure, volume of a gas of a fixed quantity is directly proportional to the absolute temperature.

Mathematically Charles's law is expressed as:

Charles's law is applicable only for ideal gases.

Bolyles's law gives relationship between pressure and volume at fixed temperature.

Gay-Lussac’s law gives the relationship between pressure of a gas and its absolute temperature.

Dalton's law gives the relationship between pressure of the mixture of non reacting gases and partial pressure of individual gas.

Therefore, among, Charles's law is the correct opion.
