Molality is the number of moles of solute per kilogram of solvent. it is denoted by "m".
A 1.0 m solution contains 1 mole of solute per kilogram of solvent. Unit of molality is moles/ kg. Molality of solution does not change with the temperature of solution. In case of molality it is ratio of moles to mass. Mass is the same at any temperature hence molality wont change with change in temperature.

Because there is no change in mass of solvent in kg but in molarity volume of liquid gets changed
