Question

a gas at constant pressure occupies a volume of 300cm³ at temperature of -73°c find its volume at 127°c pressure remains constant

Answer 1

GIVEN INFORMATIONS :

V1 = 300 cm³

T1 = -73°C = 200 K

V2 = ? cm³

T2 = 127°C = 400 K

By Charles' Law,

V1/T1 = V2/T2 (Pressure=Constant)

Or, 300/200 = V2/400

Or, V2 = (3×200) cm³

Or, V2 = 600 cm³ [ANSWER]
