प्रश्न
What is meant by apparent expansion and real expansion of a liquid?
एका वाक्यात उत्तर
उत्तर
When a liquid is heated in a flask. Due to heat, the flask expands along with the liquid, thus providing more space for the liquid. Hence the level of the liquid falls. Thus this dropped level shows the apparent expansion of the liquid. The actual expansion of the liquid, when heated, is the real expansion.
