20 Examples Of Physical Phenomena In Daily Life

Physical phenomena are those changes that a substance undergoes without altering its nature, properties or constitution.  there is simply a change of state, shape or volume.

Physical phenomena also occur when a body moves or is transferred from one point to another. These types of phenomena are also identified by being reversible .

Physical phenomena are then opposed to the so-called chemical changes , which occur precisely when there is a transformation in the nature or composition of the substance. Or, when a new one is produced.

This happens for example when we bring a piece of paper close to the flame of a candle. After the paper catches fire, we can see that it has turned into ash. In this case then we are faced with a chemical phenomenon since the paper, together with the fire, was transformed into ashes.

As can be seen, these phenomena are not reversible, since these ashes cannot be converted back into paper. As if it happens, for example, with an ice cube that melts. It can return from a liquid state to a solid state if it is placed back in the freezer.

20 Examples of physical phenomena are:

  1. When we put water in a saucepan and put it on the fire until it boils. In this process, water goes from a liquid state to a solid state.
  2. When the sea tide rises and falls.
  3. When we wash our hands with water and then put them under the hand dryer, it evaporates and we dry out.
  4. When we kick a soccer ball and it moves from one point on the field to a different one.
  5. The characteristic rotation and translation movements of planet Earth.
  6. When we dissolve a handful of salt in water. Although it is dissolved, it does not lose its properties.
  7. The change in temperature throughout the day.
  8. When we sand the surface of a wooden board.
  9. When glass is exposed to fire, it softens and becomes malleable. Although its state changes, its nature remains the same.
  10. When we break a piece of cement into several pieces.
  11. When sand and water are placed in the same bucket.
  12. When the mercury in a thermometer expands as a result of contact with high temperatures.
  13. When the ethyl alcohol that was in its bottle evaporates. It thus goes from liquid to gaseous state, without losing its properties.
  14. When we make papel picado with sheets of paper for a birthday party.
  15. When a feather is suspended in the air for a while.
  16. When a breeze or wind blows.
  17. When we mold a piece of clay and give it a different shape than the one it had at the time we found it.
  18. The water cycle: in this, water goes through its three states, which are solid, in the form of ice or snow, liquid, which we can find in seas , rivers and lagoons , and gas, which is observed in clouds.
  19. When a piece of metal is melted , such as silver. This then goes from solid to liquid state.
  20. When a frisbee or boomerang is thrown into the air.
