Answer to Question #196769 in General Chemistry for cameron iles

Question

If temperature is constant at 30°C, and pressure decreases from 1.4atm to 0.1atm, which is phase change?

Answer 1

P₁ / T₁ = P₂ / T₂ .

1.4 / 303 = 0.1 / T₂

T₂ = 303 × 0.1 / 1.4 k = 21.64 k .

If temperature is constant and pressure will decrease than liquid changes into gas .

Solid changes into liquid .
