Question

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

Answer 1

A

Step-by-step explanation:

Answer 2

P1 /T1 =P2/T2

Step-by-step 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
