Name one metal which does not react with oxygen when heated?
Brooks metal ;)
Give one advantage of making the frame from smart alloy instead of an ordinary metal?
It can go back to its original shape when it is heated.
Why does the conductivity of a metal increase when a metal is cooled?
conduction is basically the flow of electrons from one end to the other in a conductor. lets take the example of a metal rod. the metal rod can conduct electricity as the electrons are able to flow and the resistance offered by the cations is relatively low. however, when the metal rod is heated, the cations start vibrating as energy is supplied to them. vibrating cations cause greater hindrance to the movement of electrons and thus, the conductivity decreases.
What is the yellow powder created when heating zinc oxide?
what happens to calcium oxide and zinc oxide when heated?
What happens at the atomic level when a metal is subjected to pressure such as a blow from a hammer?
The metal cations easily slide past one another.
When one end of a piece of metal is heated what happens?
the partcles get closer together or the particles get bigger. you decide
When a metal rod is heated at one end which end is hotter?
The end that is being heated should be hotter than the other end.
What happens when one end of a metal slab is heated and ice is placed on the other end?
Heat will be transferred through the metal and begin melting the ice at the other end. Metal is a very good conductor of heat and heat like most other things prefers to equalize itself if possible.
When a metal rod is heated at one end what energy transfer takes place in the rod?
conduction
What happens when heat moves by conduction from one end of a metal spoon to another?
Particles move from one end of the spoon to the other
Name one metal which does not react with oxygen when heated?
Brooks metal ;)
Can one produce energy with a bi metal strip when heated?
Yes
WHY is metal a good condutor of heat?
it is because of the mobile electron pool. due to this electron arrangement metal ions are so closely packed, when one end is heated the ions in that end vibrate.this results the neighbouring ions to vibrate one by one. thus thru vibration heat is carried from one end to the other. since such an arrangement is found only in metals,metals are good thermal conductors..
If two similar pieces of metal are heated one to red hot and the other just hot are plunged into water why does the hotter piece cool the quickest?
metal
What happens when one piece of metal is melted?
It becomes hot liquid.
What happens when a ionic bond forms?
Electrons are tranferred from one atom to another. Typically from a metal to a non-metal
Why do metal bridges have gaps at one end?
So it can expand
