Question

An iron sphere has a radius of 10 cm at a temperature 0C.Calculate the change the volume of the if it is heated to 100C.Co efficient of linear expansion is 11×10^-6​

Answer 1

Change in volume:

$\delta V = 3 \times Coefficient \times V_0 \times \delta T \\\\ => 3 \times 11\times10^{-6}\times \frac{4}{3} \times \pi \times10^3\times100 \\\\ =>1.3816cm^3$
