The concentration terms such as mass percentage, ppm, mole fraction and molality are independent of temperature. However, molarity is a function of temperature. Explain.

Molarity of a solution is defined as the number of moles of the solute dissolved in 1 L of the solution.
Molarity=Number of moles of soluteVolume of solution in liters
When temperature increases, the volume of the solution also increases, assuming the solution is at a constant pressure condition
Therefore, when temperature increases, volume increases and molarity decreases.
Other concentration terms such as mass percentage, ppm, mole fraction and molality are only dependent on mass, which is independent of temperature.
Hence, the concentration terms such as mass percentage, ppm, mole fraction and molality are independent of temperature, however, molarity is a function of temperature.
