What is the percentage change in length of `1m` iron rod it its temperature changes by `100^(@)C. alpha` for iron is `2 xx 10^(-5)//"^(@)C`.

What will be the change if silver rod is used instead of iron rod? What is the reason?

An iron sphere has a radius 8 cm at a temperature of 0^(@)C . Calculate the change in volume of the sphere if is temperature is raised to 80^(@)C . Coefficient of liner expansion of iron =11xx10^(-6) .^(@)C^(-1) .

Length of a metal rod at temperature 27^@ C is 4.256m. Find the temperature at which the length of the same rod increases to 4.268m. ( alpha for iron = 1.2 xx 10^(-5) K^(-1) )

An iron sphere has a radius of 10 cm at a temperature of 0^(@)C . Calculate the change in the volume of the sphere, if it is heated to 100^(@)C . Coefficient of linear expansion of iron = 11 xx 10^(-6).^(@)C^(-1) .

A clock with an Iron Pendulum keeps correct time at 20^(@)C How much will it lose or gain if temperature changes to 40^(@)C ? [Given cubical expansion of iron =36xx10^(-6)""^(@)C^(-1) ]

The length of s steel rod exceeds that of a brass rod by 5 cm. If the difference in their lengths remains same at all temperature, then the length of brass rod will be: ( alpha for iron and brass are 12xx10^(-6)//^(@)C and 18xx10^(-6)//^(@)C , respectively)
