Question

calculate the volume of 47 cm^3 of gas at 27°c ,would occupy at 22°c at constant pressure​

Answer 1

Volume 1 = V1 = 47 cm^3

Temperature 1 = T1 = 27°C

Volume 2 = V2 = ?

Temperature 2 = T2 = 22°C

By using Charles' law, where pressure is constant (∆P = 0), we get

V/T = constant

or, V1/T1 = V2/T2

by putting the respected values, we get

(47)/(27) = V2/(22)

or, (47)/(27) = V2/(22)

or, (47)(22) / 27

or, 38.3 ≈ V2

At 22°C, the gas will occupy 38.3 cm^3 of volume at constant pressure.
