Question

in a closed vessel of 400 k temperature the pressure of cl2 gas is 4 bar . At which degree Celsius the gas is having pressure 5 bar.
​

Answer 1

Answer:

We know that

T

1

P

1

= constant for constant volume.

Let the initial pressure be P

1

and initial temperature be T

1

.

Thus final pressure P

2

=1.004P

1

and final temperature T

2

=T

1

+1.

Using

T

1

P

1

=

T

2

P

2

So,

T

1

P

1

=

T

1

+1

1.004P

1

Or T

1

+1=1.004T

1

Or 0.004T

1

=1

⇒T

1

=250K
