take three similar milk bottles and fill one of them with kerosene oil,one with water and one with any other vegetable oil. fixsoda straw in them with help of cork and mark the level of each liquid in soda straw. place the bottle in trough .pour hot water in the trough. watch the level of each after few minutes what do you observe.list your observation with suitable reasonl.

The question require the coefficient of volumetric expansion of kerosene, water, oil and glass. If coefficient of expansion of liquid is greater than that of glass liquid will rise up in straw otherwise itt will come down

THE LIQUIDS  LEVEL AND THEIR EXPASION WOULD B DIFFERENT......


AND  IF THE EXPANSION OF LIQUID IS MORE THAN TAT OF GLASS THE LEVEL INCREASES......


KEROSENE LEVEL HAS INCREASED MORE THAN THAT OF OIL AND WATER............


AS KEROSENE HAVE GREATER COEEFICENT OF THERMAL EXPANSION.............
