Question

If Flask containing nitrogen has volume 10L was heated from 273K to 546K. the pressure in the container doubled, if same flask containing Methane is heated from 300K to 500K. The percentage of air escaped to the atmosphere is nearly.​

Answer 1

Answer:

ANSWER

Given that:

T

1

=300K,T

2

=300K

Let V

1

=V, then V

2

=?

So, V

2

=

T

1

V

V

2

=

T

1

V×T

2

=V×

300

500

V

2

=

3

5V

So, volume of air escaped = (V

2

−V

1

)

=(

5V

−V)

=

3

5V−3V

V

=

3

2V

So, percentage of air escaped =

2V

×100×

5V

=40%

So, the correct option is B
