The quantity which changes with temperature is:

Options

  1. AMolarity
  2. BMass percentage
  3. CMolality
  4. DMole fraction

Correct answer

A. Molarity

Step-by-step solution

Molarity = No. of Moles of solute Volume of solution in L Since volume depends on temperature, molarity will change upon change in temperature. As the temperature rises, the volume of the solution increases. When the temperature increases the molarity of the solution will decrease as temperature depends on volume. Hence option A is the answer.
