Which of the following concentration terms is dependent on temperature?

1. Mass %, ppm, mole fraction and molality are all defined using masses or mole counts, which do not change with temperature. 2. Molarity is moles of solute per litre of solution, and volume of solution expands or contracts with temperature. 3. Hence molarity is a function of temperature, while the others are temperature independent. _Source: syllabus Chemistry Ch 1 "Solutions", p.4_
