1.	Arrange the following steps in a sequential order to demonstrate the thermal expansion of solids (a) heat th eball with a spirit lamp for some time (b) place the ball on the ring it just slips through the ring (c ) Place the ball on the ring the ball does not pass through the ring (d) take a ball and ring such that the internal diameter of the ring and the external diameter of the bal are equal .
Answer» DBAC dabc dacb dcab Solution :First take a ball and rightsuch that the INTERNAL DIAMETER of the ring and the eternal diameter of the ball are EQUAL (d) .Place the abll onthe ring it just slips through the ring (b) Now heat theball witha spirit LAMP for some time (a) and then again place the ball onthe ring the ball does not pass through the ring (c ) This expains that the ball expands on heating and it does not pass through the ring
