What is a example of conduction?
A wire carrying electricity to a load. The wire conducts the energy from a source to a device. That connection in a complete circuit does work.
Is wood a good conductor of sound?
Some types of wood are, other types are not.
Why iron nail pierces the wooden plank easier with its pointed end?
a nail is sharp because the sharper the nail is, the thinner the tip is, which in turn can more easily get in between the molecules of the wood, so you can then push/smash your way into the wood, and as the width of the nail gets wider, it pushes apart the molecules, in turn, clearing the path for the nail to get through. PS. this is just common sense.
What is an iron nail reactive with when forming rust?
oxygen, the air around us, it 'oxidises' so forms a layer of iron oxide or 'rust' , and im only 16!! ahaa
Is it advisable to use wooden sphere for the dome of a van de graaf genarator?
No wood is a poor conductor of electricity. You would want a good conductor (a metal).
How good is metal a conductor?
Metal is a very good conductor, because it transefers electricity, through its atoms. Kind of like how water is a strong conductor. This is so because of the amount of iron a item has. rubber is a insulator because is has very low iron, and wood is also, unless it has a metal nail in it, of course.
Which of these materials is the best conductor of heat air iron water or wood?
Iron is the best conductor. Metals in general are good conductors of heat because of their delocalised electron bonding.
Why is wood the best conductor?
Wood is not a good conductor.
Which of the these are the best conductor of heat wood plastic cloth iron?
iron
Is a matchstick magnetic?
No, they are made of wood or paper, and are not magnetic. An iron nail is attracted to a magnet, and can become magnetized.
Why does a piece of iron feel colder than a piece of wood even though they are both in the same temperature?
Wood is a porous material in which a lot of air is trapped, and as a result, it is a poor conductor of heat. Iron is a denser material which is a good conductor of heat. So when you touch iron, heat flows easily from your finger into the colder piece of iron. Heat flows much more slowly from your finger into a piece of wood, even if the wood is exactly the same temperature as the iron.
Which of these is a good conductor wood paper silver or air?
Gold: Insulator* Wood: Insulator Tin: Conductor Plastic: Insulator Cotton: Insulator* Silver: Insulator* Wool: Insulator* Aluminium: Conductor Copper: Conductor Iron: Conductor Rubber: Insulator Air: Insulator* All answers that I have marked with an asterisk (*) are answers that I am pretty sure about but not entirely 100% positive. Not all my answers will be correct but I am fairly sure most of them are. :)
Is wood a good heat conductor?

Is wood good conductor of electricity?
No.
Is wood good a heat conductor?
no it is not.
What are some examples of insulators of electricity?
Wood, plastic, glass, --> holds electrons tightly. opposite of conductors.
Is wood a insulater or conductor?
Wood is a very good insulator
