Q. The depression in freezing point (ΔTf) of a solution is related to the molality (m) by:

किसी विलयन के हिमांक (ΔTf) में अवनमन मोललता (m) से इस प्रकार संबंधित होता है:

A
ΔTf = Kf × m
B
ΔTf = Kf/m
C
ΔTf = Kf × m²
D
ΔTf = Kf/m²

Explanation

Freezing point depression depends linearly on molality:

ΔTf=Kf×m\Delta T_f = K_f \times m
