When A Copper Ball Is Heated, The Largest Percentage Increase Will Occur In Its: 

The sprinkling of water reduce the temperature of a closed room because: 

Two bars of copper having same length but unequal diameter are heated to the same temperature. The change in length will be:  

The beaker is completely filled with water at 4^oC. 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 (α₂ > 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:

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