The density of liquids and gases changes with temperature because the change in temperature changes the volume of the substances.
Hence, the statement is true.
Assertion (A) Molarity of a solution in liquid state changes with temperature. Reason (R) The volume of a solution changes with change in temperature.
The density of liquids and gases change with temperature because there is a change in their mass.
Assertion: Molarity of a solution in liquid state changes with temperature.
Answer the following questions in short.
