How does molarity change with temperature?

Answer: It is well known that the volume of the solution affects molarity. Temperature immediately affects a solution’s volume, which is known to rise as the temperature rises. As a result, the relationship between molarity and temperature is inverse.

A drop in the number of moles per litre will follow a rise in temperature since it will be accompanied by an increase in the volume of the solution (since the amount of solute remains the same throughout). As a result, it is well known that molarity declines as temperature rises.
