Answer 2

Explanation:

1. Renewable Energy. These sources are natural sources of energy and has zero emission in comparison to the fossil fuels.

2. Renewable Energy. As Sun light is natural and will last forever.

3. Taking long, hot showers. As this activity is resulting in waste of energy it can not show energy conservation.

4. Conservation of Energy. According to the law the total of all the energy in an isolated system remains constant i.e. conserved.

5. Turning off the lights when you are not in a room. As this activity is resulting in saving energy.

6. Stored energy. Potential energy is the energy stored or held by any object because of its position.

7. Always to a place of lower thermal energy. The flow of thermal energy causes heat and it always moves from high temperature to low temperature.

8. Use our energy resources wisely. Conservation of energy means using the resources wisely. You might think that we should recycle all of our energy. But most of the time that is not possible.

9. Conservation of Energy. According to the law the total of all the energy in an isolated system will always remain constant i.e. conserved. It means it cannot be destroyed or created. It can only be converted from one type of energy to another.

10. By either moving liquids or moving air currents. Convection is a process of energy transfer where hot particles of liquid or gas move up loses energy, dive down and are replaced by hotter particles.

11. Potential energy. Potential energy is the energy stored. In the batteries chemical energy is stored which get converted to electrical energy for the flashlight to work.

12. Conduction. As the heat energy will be transferred through the water molecules which are in contact with each other.

13. Insulators. These are the objects which do not conduct heat well. Example: Wood.

14. Radiation. The energy of the Sun or stars is transferred through electromagnetic radiations.

15. Convection. In convection the heat is transferred through the motion of particles. Here the hot water will move up and cold water will move down.

16. Thermal energy moves to an object with less heat.

17. Burning your finger on a hot match. Because for conduction to happen the two objects must touch each other.

18. Potential energy.

19. Energy is never being created or destroyed.

20. Touching each other.
