प्रश्न
For a given heat in liquid, the apparent expansion is more than that of real expansion.
पर्याय
True
False
उत्तर
For a given heat in liquid, the apparent expansion is more than that of real expansion - false.
Correct Statement:
When the liquid is heated in a container, first heat is gained by container which expands and the level of liquid goes down, but immediately liquid receives the heat from container so apparent expansion is liquid.
Real expansion = Expansion of container + Apparent expansion
APPEARS IN
