Answer
The following experiment demonstrates that same volume of different liquids heated to same rise in temperature expand by different amounts:
- Take four identical glass bottles each fitted with a narrow glass tube through a cork at its mouth.
- Fill them up to the same level with different liquids like water, alcohol, kerosene, benzene.
- Place them in a common water bath containing boiling water as shown in figure.
Observations — After sometime it is noticed that different liquids rise to different levels. Benzene expands the most followed by alcohol and kerosene. Water expands the least.
Conclusion — From the above experiment it is concluded that, same volume of different liquids heated to same rise in temperature expand by different amounts.
