Question

Which law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume conditions?
A. Boyle’s law
B. Charles’s law
C. Dalton’s law
D. Gay-Lussac’s law

Answer 1

Gay Lussac’s law state that the pressure and absolute temperature of a fixed quantity of a gas are directly proportional under constant volume conditions.  

Further Explanation

Gay-Lussac’s law  

• It states that at constant volume, the pressure of an ideal gas I directly proportional to its absolute temperature.
• Thus, an increase in pressure of an ideal gas at constant volume will result to an increase in the absolute temperature.

Boyles’s law  

• This gas law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature.
• Therefore, when the volume of an ideal gas is increased at constant temperature then the pressure of the gas will also increase.

Charles’s law

• It states that the volume of a fixed mass of a gas is directly proportional to absolute temperature at constant pressure.
• Therefore, an increase in volume of an ideal gas causes a corresponding increase in its absolute temperature and vice versa while the pressure is held constant.

Dalton’s law  

• It is also known as the Dalton’s law of partial pressure. It states that the total pressure of a mixture of gases is always equivalent to the total sum of the partial pressures of individual component gases.
• Partial pressure refers to the pressure of an individual gas if it occupies the same volume as the mixture of gases.

Answer 2

The Gay-Lussac’s law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume.

Further Explanation:

The Boyle’s Law states that the pressure of a gas is inversely proportional to the volume of the pressure when the temperature of the system is kept constant. It means that if the pressure of the gas is increased, the volume occupied by the gas has to decrease.

$P \propto \dfrac{1}{V}\,\left( {{\text{at}}\,{\text{constant}}\,{\text{temp}}{\text{.}}} \right)$  

The Charles’ Law states that the volume of a gas is directly proportional to the temperature of the gas when the pressure of the system is kept constant. It means that if the volume of the gas is increased, it increases the absolute temperature of the gas at constant pressure.

$V \propto T\,\left( {{\text{at}}\,{\text{constant}}\,{\text{pressure}}} \right)$  

The Dalton’s Law states that the total pressure of a gas is equal to the sum of the partial pressure of all the component gases present in the system.

 $P = {P_1} + {P_2} + {P_3}....$    

The Gay-Lussac’s Law states that at a constant volume, the pressure of a gas is directly proportional to the temperature of the gas. It means that the temperature of gas is increased if the pressure of the gas is increased at a constant volume.

$P \propto T\,\left( {{\text{at}}\,{\text{constant}}\,{\text{volume}}} \right)$

Thus, the Gay-Lussac’s law states that the pressure and absolute temperature of a fixed quantity of gas are directly proportional under constant volume.
