Answer: The final volume V_2 is 263.09 ml

Explanation:

To calculate the final volume 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=156ml\\T_1=215^oC=(215+273)K=488K\\V_2=?\\T_2=550^0C=(550+273)K=823K

Putting values in above equation, we get:

\frac{156}{488}=\frac{V_2}{823}\\\\V_2=263.09ml

Thus final volume V_2 is 263.09 ml
