Conduction Experiment by Cassidy Perez [Student FVHS]

What is conduction?

2014-04-04 17:32:39 UTC

Conduction is the process by which heat or electricity is

directly transmitted through a substance when there is

a difference in temperature or electrical potential between

adjoining regions without movement of the material.

What is heat?

2014-04-04 17:39:27 UTC

Heat is a form of energy that causes a difference in tempature

or the perception of warmth.

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

17poctamg253 — 2014-04-04 17:44:57 UTC

The wire that conducted the most heat was our thickest wire. The wire got very hot and the wax melted off of that wire first and that's how we know that the thickest wire conducted the most heat

Why is wire the best conductor of heat?

The best conductors of heat depend on their metallic properties.

Copper is a good conductor because of the amount of free electrons

in its metallic structure. The structure of copper allows electrons to

move more quickly. Since our copper wire was thicker the molecules

are able to conduct heat more quickly because there is more surface

area.

Which of the ESLR's was addressed in this activity.

During our conduction experiment, we were all being responsible members of society because we were working well with each other and we were being mature while working with the fire and hot wires.

Experiment Setup

How was conduction demonstrated by the experiment we are doing with the candle, wire and wax?

17perezcd109 — 2014-04-04 17:58:01 UTC

Conduction was demonstrated by the experiment we did with the candles wires and wax. Conduction was demonstrated with these three things because the candles transferred the heat from their flames into the wire which the heat then transferred to the wax which melted off of the thickest wire.
