Which formula should be used to calculate pressure and temperature changes if the volume remains constant

a
p1t1=p2t2

b
v1t1=v2t2

c
p1v1t1=p2v2t2

d
p1v1=p2v2

P1 /T1 =P2/T2

Explanation:

ccording to the Gay- Lussac's Law,

" The pressure of given amount of gas is directly proportional to the temperature at a constant volume"

Mathematical expression:

          P ∝ T

         P = CT

         P / T = C

As the temperature increase, the pressure also increase and vice versa.

The initial and final expression of volume and pressure can be written as,

P₁ / T₁  = P₂ / T₂

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
