The terms speed and velocity are sometimes confused although they have different meanings.

Concept of speed and mass of the electrons

The educational resource shows an interactive animation about the specific heat concept: when a body is heated, the temperature it finally reaches depends on the nature of the body. This property is known as specific heat.

Soddy and Fajans stated the laws of transmutation which govern the process by which one element transmutes into another. Soddy's 2nd law: When a radioactive atom emits a beta particle, its atomic number increases by one unit.
