WebJul 31, 2024 · Molarity is a temperature-dependent parameter. The volume of a solution increases with an increase in temperature diye to increase in intermolecular spaces and vice versa. Hence, molarity is affected by temperature change. As Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. WebThe temperature effect depends on the nature of the solute and the solvent, and their interactions. These are completely different between solid solutes and gaseous ones. The propensity of a solid is to become more soluble as temperature goes up, and for a gas to become less soluble.
