Question

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

Answer 1

Answer:

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
