An ideal gas in a sealed container has an initial volume of 2.50 L. At constant pressure, it is cooled to 21.00 ∘C, where its fi
goblinko [34]

<u>Answer:</u> The initial temperature of the system comes out to be 147 °C

<u>Explanation:</u>

To calculate the initial 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.

We are given:

V_1=2.50L\\T_1=?K\\V_2=1.75L\\T_2=25^oC=(25+273)K=294K

Putting values in above equation, we get:

\frac{2.50L}{T_1}=\frac{1.75L}{294K}\\\\T_1=420K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

420=T(^oC)+273\\T(^oC)=147^oC

Hence, the initial temperature of the system comes out to be 147 °C
