1. What is conduction? What is heat as defined in science?

17tontitn012 — 2014-04-03 23:25:52 UTC

Conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. Heat is the process of energy transfer from one body or system due to thermal contact, which in turn is defined as an energy transfer to a body in any other way than due to work performed on the body.

3. Which of the wires conducted heat the best (melted the ball of wax first)?

17tontitn012 — 2014-04-03 23:33:19 UTC

The thickest wire conducted heat the best.

4. Explain with at least 2 sentences why that wire is the best conductor of heat. (Make sure to mention how the thickness of the wire helped your results).

The wires are made of the same substances but the different sizes do not transfer electrons equally. In a thicker wire, it gives the electrons more room to "flow" faster and heat up and in a thinner wire there is less space so it wont move as fast. That is why the thickest wire melted the wax first, then the middle sized one, and then the thinnest one was last.

2. Explain how conduction is demonstrated by the experiment that you are doing with the candle, wire, and the wax.

17spasovpn012 — 2014-04-05 01:10:43 UTC

The conduction in this experiment is transferred from heat of the candle of the candle to the wire and then making the wax fall off the wire. It takes a about 5 mins to 40 mins for the wax to fall off the thickest wire depending on how much heat is conducted into the wire.

5. Which of the ESLR's was addressed in this activity. Explain with a couple of sentences.

17spasovpn012 — 2014-04-05 01:11:37 UTC

The ESLR that was addressed in this activity was critical thinker. You have to be a critical thinker in this experiment because you have to know how the heat is transferred in the copper wire. You also have to know to place the 3 copper wires in the most effective place so the heat gets transferred. And you also have be patient and wait for the wax to fall off the copper wire.
