Question

Gas in a closed container at temperature of 27 C has pressure P. what will be the pressure if temperature is raised to 127 C?

* 4 P / 3
* 27 / 127 P
* 3 P / 4
* 127 P / 27​

Answer 1

Answer:

Correct option is

C

4P

The gas equation states that,

PV=nRT

So, we can conclude that,

P∝T

Hence,
