Question

At what pressure a quantity of gas will occupy a volume of 60 ml if it occupies a volume of $100ml$ at a pressure of $720mm$, assuming the temperature is constant?

• A. $700mm$
• B. $800mm$
• C. $100mm$
• D. $1200mm$

Answer 1

The correct option is D $1200mm$

Given :- $P_1=720$ mm

$V_1=100ml$

$V_2=60ml$

$P_2=?$

Temperature is constant

$P_1{V}_1=P_2{V}_2$

$720\times 100=P_2\times 60$

$P_2=\frac{720\times 100}{60}$

$P_2=1200mm$

Hence, the correct option is $\text{D}$
