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.

WebMay 31, 2024 · Why does molarity change with temperature? Molarity is dependent on temperature, whereas molality is not. … Molarity is solute moles per litre of solution. As the temperature increases, water expands, so the solution’s volume therefore increases. In more litres, we have the same number of moles, but the molarity is smaller at higher ... WebJan 27, 2014 · Explanation: Molarity changes with temperature. Molarity is moles of solute per litre of solution. Water expands as the temperature increases, so the volume of the solution also increases. You have the same number of moles in more litres, so the molarity is less at higher temperatures. EXAMPLE
