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

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
