Question

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

Answer 1

Answer: B. Charles’s law

Explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

Boyle's law law states that pressure is directly proportional to the volume of the gas at constant temperature.

Gay-Lussac Law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
