-- The job won't get done unless the heat can reach the food.
-- The heat is outside the saucepan.
-- The food is inside the saucepan.

Is air a good conductor of electricity?
Air is a relatively-very-poor electrical conductor. If it were any good as a conductor,then you would need to keep your spare batteries in vacuum containers, to preventtheir becoming discharged through the air between their terminals.
What is a conductor of static electricity?
static electricity doesn't really need a conductor, a high enough voltage will cause electrons to jump a distance, without a conductor, as long as there is no insulator involved. All you need is a sufficient amount of free electrons on one side, say your finger tip, and a good ground on the other side, try a car door handle.
Why can't you charge metals by rubbing?
Because the metal is conductive, therefore its surface is incapable of holding a static charge.
What 2 things do you need for a current to flow?
Potential difference and the conductor. A cell and a bulb. Some connecting wires. The bulb can be made glow by connecting the wires with the cell.
Activity to show that water is bad conductor of heat?
Water is a relatively good conductor of heat. I said "relatively" because it depends on what you compare it with. To show that it is a bad conductor of heat, you need to compare it with something that is even better conductor of heat (i.e. metal). What you can do: Use 2 fresh ice cubes that are similar in size. Put one inside a cup of water in room temperature. Wrap the other one with aluminium foil. Observe and you will see that the one that is wrapped with aluminium foil melts faster.
What part of a saucepan needs to be a thermal conductor?
The base,main part of the pan and the bits that need to be insulators are the holder on the lid and the handle
Why must the connectors of an electrical circut be made of a material that is a good conductor?
I don't know?? Thats why I was on here to get an answer because i have a stupid homework due tomorrow and I need an answer!!
Objects which need a good conductor of electricity to work?

What are the basics of how flashlights work?
You need a conductor, power source and a resistor. You need a conductor, power source and a resistor. You need a conductor, power source and a resistor.
Why are saucepans not made form gold?
While a good conductor of heat, gold is rare and exceptionally expensive. Cheaper metals perform equally as well, so there is no real need to use gold for this.
Electron move without potentiel difference in a conductor?
No. In a good conductor you simply need less potential difference than in a bad conductor, to get the same current. But if you have zero voltage, you will also have zero current. Unless you have a superconductor (zero resistance), and the current is already flowing.
Does a string quartet need a conductor?
Yea because a string quartet needs a conductor
Why is hydrogen chloride good conductor of electricity?
What you need to remember that Hydrogen is H+ plus an electron e- Therefore it conducts electricity and a good heat conductor. Also creates water when bonded with Oxygen, very important in photosynthesis, cellular respiration and our everyday life ;)
What are computer wires made up of?
Most are currently made of copper. In the past, some were made of silver and even gold. Silver is a better conductor than copper, and gold is a better conductor than silver. As you can imagine, both are rather cost prohibitive.

Does the Wind Ensamble need a conductor?
Yes, it does
