R P Rana Solutions for Chapter: Matter, Exercise 2: Check Point

Define the law of conservation of mass.

What is mass-energy equation given by scientist Albert Einstein?

$\left(\mathrm{A}\right) \mathrm{E}=\mathrm{mc} \left(\mathrm{B}\right) \mathrm{E}={\mathrm{mc}}^2 \left(\mathrm{C}\right) \mathrm{E}={\mathrm{m}}^2\mathrm{c}$

Enter your correct answer as $\mathrm{A}, \mathrm{B}$ or $\mathrm{C}$.

Name the scientist who told that mass can be converted into energy.

Describe in short with the help of an experiment how the law of conservation holds.
