Question

Volume of a gas at $o^{o}C$ is doubled at constant pressure and amount of gas. What is a new temperature?

• A. $273k$
• B. $O^{o}C$
• C. ${273}^{o}C$
• D. ${127}^{o}C$

Answer 1

The correct option is C ${273}^{o}C$

Acoording to ideal gas equation $PV=nRT$

$V\alpha T;\frac{V_1}{T_1}=\frac{V_2}{T_2}$

$\frac{V_1}{273K}=\frac{2V_1}{T_2}$

$\therefore T_2=273\ast 2=546K=>{273}^{0}C$
