24. A sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °C). If the ball is then played with o
baherus [9]

<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

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

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}        (at constant volume)

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

Conversion factor:  T(K)=T(^oC)+273

P_1=1.85atm\\T_1=25^oC=(25+273)K=298K\\P_2=?atm\\T_2=7.5^oC=(7.5+273)K=280.5

Putting values in above equation, we get:

\frac{1.85atm}{298K}=\frac{P_2}{280.5K}\\\\P_2=1.74atm

Hence, the correct answer is Option B.
