Question

Question 5.1 What will be the minimum pressure required to compress 500 dm^3 of air at 1 bar to 200 dm^3 at 30°C?

Class XI States of Matter Page 152

Answer 1

temperature is constant in both conditions e.g., T = 30°C or 303K .so we have to apply Boyle's law of gaseous theory.
$e.g.,P_1V_1=P_2V_2$
Here, P1 = 1 bar , V1 = 500 dm³,
V2 = 200 dm³ , P2 = ?

now, 1 bar × 500 dm³ = P2 × 200 dm³
P2 = 2.5 bar

hence, minimum pressure required to compress is 2.5 bar

Answer 2

Answer:

The pressure will be 2.5 bar.
