Why is molality almost unaffected by temperature?

Answer and explanation
Correct answer: Because it is based on mass of solvent
Molality uses moles of solute per kilogram of solvent. For a fixed sample, mass does not appreciably change when temperature changes, unlike volume. Hence molality is considered temperature-independent in ordinary calculations. It is not based on colour, pressure, or restricted to gases.
