Question

what is the effect of temperature on molarity?

Answer 1

Molarity is affected by the temperature . molarity  is the ratio between number of moles of solute to the volume of solution in litres and as on increasing temperature the  volume increases and hence with the increase in temperature the molarity of solution decreases .

molarity is directly proportional to the temperature 

Answer 2

Molarity is affected by temperature because it is based on the volume of the solution, and the volume of a substance will be affected by changes in temperature.
