Statement I: When a solid iron ball is heated, percentage increase in its volume is largest.
Statement II: Coefficient of superficial expansion is twice that of linear expansion where as coefficient of volume expansion is three times of linear expansion.
In the light of above statements, choose the most appropriate answer from the options given below
Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct. As 
and 
, i.e. coefficient of volume expansion of solid is three times the coefficient of linear expansion and 1.5 times the coefficient of superficial expansion, on heating a solid iron ball, percentage increase in its volume is largest.
