Question

What is the effect of temp.on molarity and molality

Answer 1

molarity is efffected by the temperature because it is based on the volume of the solution, and a volume of the substance will be affected by changes in temp.in general,volume will increase when temp increases,and vice versa.

molality is the no. of moles of solute per kilogram og solvent...molality of solution does not change with the temp of solution.In case of molality it is the ratio of moles to mass.mass is the same at  any temp hence molality wont change in the change of  the temp..

Answer 2

Explanation:

◾Effect of temperature on molality and molarity :-

➡ Molarity is effected by the temperature because it is based on the volume of the solution,,and a volume of the substance will be affected by change in temperature ,, in general,,voulme will increase when temperature increase...

➡ Molality is the number of moles of solute per kilogram of solvent..

Molality of solution doesn't change with the temperature of solution..Incase,,of molality it is the ratio of moles to mass.....Mass is the same at any temperature.

Hence,,,molality won't be change in the change if temperature...
