What are the causes for the change of seasons on the earth? Earth has seasons because its axis is tilted. Earth’s axis is always pointed in the same direction, so different parts of Earth get the Sun’s direct rays throughout the year. What is Leap Year very short answer? In an ordinary year, if you […]
What are the methods of producing induced emf?
What are the methods of producing induced emf? The induced emf can be produced by changing : (i) the magnetic induction (B), (ii) area enclosed by the coil (A) and. (iii) the orientation of the coil (θ) with respect to the magnetic field. What is the use of induced emf? A motor has coils turning […]
What is the meaning of external development?
What is the meaning of external development? External growth (also known as inorganic growth) refers to growth of a company that results from using external resources and capabilities rather than from internal business activities.

Is thermal energy removed or added in boiling?
Is thermal energy removed or added in boiling? particles, rise to the top of the liquid and escape from the container. In the graph above, notice the energy changes that occur as thermal energy is added. The kinetic energy of particles increases until the liquid reaches its boiling point. At the boiling point, the potential […]
