Question

If pressure of a system is halved, then volume of the gas at isotherm is​

Answer 1

Answer:
During compression, the volume (V) of a gas decreases. When this happens, the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant, reducing the temperature (T) also causes the gas to compress.

Answer 2

Answer:

Double to the initial

Explanation:

let,

Initial pressure = P1. Initial volume = V1

final pressure = P2 = P1/2. Final volume = V2 = ?

t1 = t2 here t means temperature

we know that,

p1/p2 = V2/V1 (because p is inversly to the v)

substitute p2 as p1/2

p1/p1/2 = v2/v2

2 = v2/v1

v2 = 2 × V1

therefore v2 = double to the initial(v1)
