Question

The temperature of gas is increased from $200\text{K}$ to $600\text{K}$ at a constant pressure. If initially the volume of gas is $10\text{cc}$, then the final volume of the gas will be (in $\text{cc}$)

• A. $30$
• B. $20$
• C. $3.33$
• D. $10$

Answer 1

The correct option is A $30$

Since, pressure is constant
$V\propto T$
$\Rightarrow \frac{V_1}{V_2}=\frac{T_1}{T_2}$
Given, $V_1=10\text{cc};T_1=200\text{K};T_2=600\text{K}$
$\therefore V_2=\frac{V_1{T}_2}{T_1}=\frac{10\times 600}{200}=30\text{cc}$
