Expert Answer:

 
Take some water, paraffin oil and benzene in 3 large test tubes. Use the markers to mark the starting height of each liquid in the test tubes. Hold the test tubes together with the rubber band so the liquids are at the same level in the glass tubing, and arrange the apparatus as shown in the diagram. Use the markers to mark the starting height of each liquid on the glass tubing. Pour the hot water into the beaker around the test tubes. Watch the height of the liquids closely as the liquids warm. After sometime, it is found that the level of liquid is different in different tubes. Water rises the least and benzene rises the most. Thus, water expands the least and benzene expands the most.
Thus, equal volumes of different liquids expand by different amounts for the same rise in temperature.
