The radius of a metal sphere at room temperature T is R, and the coefficient of linear expansion of the metal is α. The sphere is heated a little by a temperature ∆T so that its new temperature is (T + ∆T). The increase in the volume of the sphere is approximately :
- 2πR α∆T
- πR2 α∆T
- 4πR3 α∆T/3
- 4πR3 α∆T
Answer
(D) 4 π R 3 α∆ T
