See the explanation.Not to be confused with molarity.

Explanation:

The mola#color(red)"l"#ity of a solution is defined as
#b=(n_(solute))/(m_(solvent))#, where
#n_(solute)#: amount of solute(in moles)
#m_(solvent)#: mass of solvent(in kg)

Since #n_(solute)# and #m_(solvent)# are never affected by the temparature, molality is also independent of temparature.

On the other hand, mola#color(blue)"r"#ity
#c=n_(solute)/v_(solution)# is dependent on the temparature, as #v_(solution)#, volume of the solution(in L), will increase if the temparature rises and vice versa.
