Molarity changes with temperature
but Molality never changes with temperature
This is the advantage of molality over molarity

Answer: Molality does not change with change in temperature.
Explanation:
Molality and Molarity, both are the units of concentration.
Molarity is defined as the number of moles of solute present in 1 L of a solution. The denominator consists of volume of solution. Volume is dependent on temperature of the system. It increases as we increase the temperature and it decreases as we decrease it. Thus, this unit will change with change in temperature.
Molality is defined as the number of moles of solute present in 1 kilograms of solvent. This unit consists of mass terms and it is independent on temperature. Thus, change in temperature will not effect this unit of concentration.
