Once the solution is prepared, water is now considered as the solvent of the solution. On the other hand, NaCl is the solute. The solvent is a substance that dissolves other substances. It has a larger composition with respect to the other components in the solution.
When we start heating to the given liquid the molecules absorbed energy and the average kinetic energy of each molecues present in liquid increased.
As the kinetic energy of molecules increases the molecules started to moves and the atraction force among the molecules decreased as a result the volume of liquid increased.
Hence option D correct explanation for given liquid.
D. When the heat was increased the liquid molecules expanded and increased in volume
Answer:
more
Explanation:
seems like you did not finish the questions
The average kinetic energy of their particles is the same
Hope this helps you =)
