Question

At constant volume and ${27}^{o}C$ the pressure of a gas is 2 atmosphere. At ${327}^{o}C$, the pressure of the gas in an atmosphere will be:

• A. 1
• B. 1.5
• C. 2
• D. 4

Answer 1

Answer: (D)

4

Given, $P_1=2$ $atm$

$T_1=300$ $K$

$P_2=?$

$T_2=600$ $K$

Since volume is constant,
Charles law is applicable, $P\propto T$

So, $\frac{P_1}{T_1}=\frac{P_2}{T_2}$

Putting all the given values, we get $P_2$ = $4$ $atm$
Option D is correct.
