the molality is temp independent whereas molarity is temp dependent. justify.

Question

unklerhaukus · Answer

liquid expands with temperature

anonymous · Answer

i did't quite get that. how is it relevant to the question? please explain

unklerhaukus · Answer

molarity is the amount of solvent per unit volume
while
molality is amount of solute per mass of solvent

molarity will change because the volume of the solvent increases with temperature

unklerhaukus · Answer

if your liquid is hot less will fit into the unit box

anonymous · Answer

However hot a substance is its weight will be same, but it expands decreasing volume, molality depends on weight whereas molarity depends on volume hence molarity changes.

anonymous · Answer

To put it simply mass of material is constant no matter what temperature. Where as volume can get smaller when it is cold or larger when it is hot.

chmvijay · Answer

mass of material is independent of temperature !!!!! and volume is dependent on temperature!!!

anonymous · Answer

Volume is temperature-dependent. which has to do with molarity. while moality is not temp dependent
