- So, if we go to Shermer we are going to be free from these problems?
- Most of them. There are some issues that Hillwood and other cities caused and affect all the planet....
- Like global warming? Can you explain me about this issue?
- Yes, that is the issue of the world. Global warming is caused by the green house effect
- And greenhouse effect is bad?
- No, it is a natural process in which gasses trap the heat from the sun on earth, making life possible in this planet
- How does this heat arrive from the sun to the Earth?
- But, how does that heat arrive to Earth?
- By radiation, it is one of the three methods of heat transfer: conduction, convection and as I said before, radiation
- By radiation. It is a method of transfer of heat. There are different types.
- Can you explain me more? I don't understand what you are saying...
- Of course. You know that heat is transferred from some bodies to others right? And that this happens because there is not an equilibrium between the heat energy each one has. This energy transfer stops when the thermal balance is found, heat is no longer transferred. Heat always travels from the body with the higher temperature to the lower
- Alright...
- The different methods work in different ways, for example, conduction works when two bodies are in contact, while convection works only in gasses and liquids, when the particles with more energy (heat) dilate and become less dense, so they rise up, and the cold particles go down, where they heat up.
