Question

When a gas is heated from ${25}^{\circ }\text{C}$ to ${50}^{\circ }\text{C}$ at a constant pressure of 1 bar, its volume:

• A. increases from $V$ to $2V$
• B. increases from $V$ to $1.5V$
• C. increases from $V$ to $1.084V$
• D. increases from $V$ to $1.8V$

Answer 1

The correct option is C increases from $V$ to $1.084V$

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
$\frac{V}{298}=\frac{V_2}{323}$
$V_2=V\times \frac{323}{298}=1.084\text{V}$
