The temperature of a gas at pressure P ...

The temperature of a gas at pressure P and volume V is `27^(@) C` . Keeping its volume constant if its temperature is raised to `927^(@) C` , then its pressure will be

A

2P

B

3P

C

4P

D

6P

Text Solution

Verified by Experts

The correct Answer is:
C
Using Charle'law `(P_(1))/(P_(2))=(T_(1))/(T_(2))`
or `P_(2)= (P_(1)T_(2))/(T_(1))= (P(273+927))/((273+27))= 4p`
