What else can I help you with?
Why can you start a fire by rubbing two sticks together but not two pieces of metal?
Rubbing two sticks together creates friction, which generates heat that can ignite the wood. Metals are better conductors of heat, so when two metal pieces rub together, the heat generated is quickly dissipated, making it difficult to generate enough heat to start a fire.
Is a fork conductor or insulator of heat?
A conductor of heat if it is made of metal.
Why does metal get hot but not wood?
Metal is a good conductor of heat, which means it can easily transfer heat from one part to another. Wood, on the other hand, is a poor conductor of heat, so it doesn't transfer heat as effectively. This is why metal objects get hot quickly when exposed to heat, while wood takes longer to heat up.
Why does metal attract more heat then other things?
Metal attracts more heat because it has high thermal conductivity, meaning it can easily transmit heat. When metal is exposed to a heat source, it quickly absorbs and distributes the heat throughout its structure, making it feel hotter to the touch compared to materials with lower thermal conductivity.
Is a metal spoon a insulator or a conductor of heat?
A metal spoon is a conductor of heat, meaning it allows heat to flow through it easily. Metals like silverware have high thermal conductivity, which is why they feel hot when placed in hot food.
Is thermal the same as geothermal?
No, thermal means heat. Geothermal(geo meaning earth, thermal meaning heat)means earth heat.
Metals are conductors of heat does this mean metal wont get hot?
Since metals are conductors of heat, that means heat can be transferred to the metal, thus the metal does get hot.

Is therme a root meaning heat?
yes. It means heat or temperature (greek)

When magnesium burns is it a metal or a non metal?
Magnesium is a metal when we say burning of magnesium it means formation of its oxide with liberation of heat and light.
Why does metal attract more heat then other things?
Metal attracts more heat because it has high thermal conductivity, meaning it can easily transmit heat. When metal is exposed to a heat source, it quickly absorbs and distributes the heat throughout its structure, making it feel hotter to the touch compared to materials with lower thermal conductivity.
Described 3 ways of fixing a piece of metal?
Welding: Joining pieces of metal together using heat to melt and fuse them. Hammering: Shaping metal by striking it with a hammer to make it thinner or bend it into a desired shape. Bolting: Securing pieces of metal together using nuts and bolts, which can be easily disassembled for maintenance or repair.
Is a metal spoon a insulator or a conductor of heat?
A metal spoon is a conductor of heat, meaning it allows heat to flow through it easily. Metals like silverware have high thermal conductivity, which is why they feel hot when placed in hot food.
What is true for 2 pieces of iron at the same temperature?
If two pieces of iron are at the same temperature, they will have the same average kinetic energy of their particles. This means that the iron pieces will not exchange heat between each other, as there is no temperature difference to drive heat transfer.
Is polystyrene a better insulator than metal?
Yes, polystyrene is a better insulator than metal. Polystyrene has a lower thermal conductivity, which means it is more effective at preventing the transfer of heat compared to metal. Metal is a good conductor of heat, so it allows heat to pass through easily.
