c) T is kept constant. Pis decreased to half d) 'T' is kept constant. P is decreased to 1/4th​

Answer 1

Answer:

We know that:

T

PV

=constant.

If volume increases by 4 times,

T

P

decreases 0.25 times.

Now all A, B, D follow the conditions but (C) where P is doubled, T decreased to half does not follow, therefore

T

P

decreases 4 times.

hope it's help you....
