Question

Describe an experiment to show that same volume of different liquids heated to same rise in temperature expand by different amounts.

Solution

CUBICAL EXPANSION OF DIFFERENT LIQUIDS IS DIFFERENT:

Experiment: Take four identical glass flasks each fitted with a narrow glass tube through a cork at its mouth. Fill flask A with water, B with kerosene, C with alcohol and D with Benzene. So that volume of each is same i.e. to the same level and their levels are visible above hot water bath. Put enough hot water in hot-water-bath. So that each flask is in the hot water. After some time we will see that different liquids rise to different levels. Water expands the least and benzene the most. This shows that different liquids of same volume expand by different amount.

  Is there an error in this question or solution?
Solution Describe an Experiment to Show that Same Volume of Different Liquids Heated to Same Rise in Temperature Expand by Different Amounts. Concept: Thermal Expansion - Volume Expansion.
