Physics - Heat & Thermo Question with Solution | TestHub

A spherical ball of radius 7 m is made up of a material having linear expansion coefficient $\alpha =2\times 10^{-5}/{}^{\circ }\mathrm{C}$ and bulk modulus $10^4\mathrm{Pa}$. If ball is heated by $20^{\circ }\mathrm{C}$ then calculate the needed excess pressure (Pa) to keep its volume constant.
