Question

To what temperature must a sample of gas initially at 27°C be heated in order to double the pressure if the volume remains constant?

Answer 1

327° C

Step-by-step explanation:

The initial temperature of the gas is 27°C

We need to find the final temperature.

If we assume the initial pressure is y

The final temperature will be 2y

Using the pressure law;

`(P1)/(T1)=(P2)/(T2)`

Therefore,

`T2=(T1P2)/(P1)`

`=((300)(2y))/(y)`

`= 600 K`

Therefore, the new temperature is 600 K or 327° C
