Question

What will be the minimum pressure required to compress 500 dm of air at 1 bar to 200
dm at 30°C
​

Answer 1

The minimum pressure is 2.5 bar

Explanation:

according to the question,

p1 = 1

p2 = ?

v1 = 500 cm3

v2 = 200 cm3

we know ,

p1 v1 = p2 v2.

p2 = p1 v1 / v2

put the value,

p2 = 500 × 1 / 200 = 2.5 bar
