A thick and a thin wire of same material and same length are heated from 10oC to 90oC. Which expands more?


Correct option is

Both show same expansion

When other variables are same, increase in length depends only on original length which is same in both cases.



The beaker is completely filled with water at 4oC. It will overflow:


When a metal rod is heated it expands because: 


Expansion during heating: 


Two rods of lengths L1 and L2 are made of materials whose coefficients of linear expansion are α1 and α2. If the difference between the two lengths is independent of temperature:  


When a strip made of iron (α1) and copper 2 > α1) is heated: 


An iron tyre is to be fitted onto a wooden wheel 1.0 m in diameter. The diameter of thetyre is 6 mm smaller than that of wheel. The tyre should be heated so that its temperature increases by a minimum of (coefficient of volume expansion of iron is 3.6× 10–5/oC):   


If the length of a cylinder on heating increases by 2%, the area of its base will increase by:


When a copper ball is heated, the largest percentage increase will occur in its: 


A rectangular block is heated from 0oC to 100oC. The percentage increase in its length is 0.10%. What will be the percentage increase in its volume?


Two rods of same material and length have their radii in ratio of 3:1, the ratio of expansion  when same amount of heat is supplied will be:
