Question

11. The pressure of a gas at 27°C is one atmospheric pressure. Keeping the volume constant, if the temperature is raised to 60°C, then its pressure will be (A) 1.11 atmospheric pressure (B) 1.5 atmospheric pressure (C) 2.2 atmospheric pressure (D) 2 atmospheric pressure​

Answer 1

Answer:

Correct option is

C

4P

The gas equation states that,

PV=nRT

So, we can conclude that,

P∝T

Hence,
