if  you hit a piece of metal with a hammer and it gets hot why do it get hot?

As the metal flexes, the molecules which make up the compound are temporarily displaced and generate kinetic energy which is dissipated as heat.   The process can be demonstrated in reverse i.e. when metal is heated, the molecules are displaced and the metal becomes pliable

Depends on the metal. Most metals generally become brittle. Iron on the addition of Carbon hardens. You may say option 2.

Holding a metal object that you touch the thing that'll shock you works. The charge still goes through your body, but it enters your hand from the object across a large area instead of via a small spark, so no one nerve is stimulated sufficiently for you to notice it.

More intense vibratory movements from the molecules mean more thermal energy transfer to the matter which become in contact with it.  So you can burn your skin if the object you touch is really too hot!

because magnesium is not a strong metal and because it is highly flamable and burns very hot and has a blinding light.

Metal objects such as the spoon & the pointed ends of the fork act to concentrate the electric field formed at the tips. This has the effect of exceeding the dielectric breakdown gradient of air, about 3 megavolts per meter (3×106V/m), causing sparks to form. This effect is somewhat analogous to the effect of St. Elmo's fire.\nMetal or conductive object placed into the microwave will act as an antenna, and its electrons will thus be thrashed back and forth through the object (a high frequency alternating current) causing some ohmic heating to occur\n\n- no damage to magnetron, but !

During a smash with a hammer two end of a metal show a potential difference. That is piezo electricity.\nDuring the smash electrons are displaced.\n\nTh

there are different tempuratures to melt gold and copper,for instance gold is a softer metal and it will melt before the copper.say the temp for melting gold is 1000 degrees,and copper is 1200 degrees,the gold will melt first.

It is not likely that it is electrical - more likely it is thermal due to friction.  A hammer hitting a rock concentrates alot of energy into the site of the impact.  The energy gets dissipated in flying bits of rock (kinetic), and frictional heating when the rock and hammer slightly deflect.\n\nj

If it hits sand, it will often make glass.  It makes the ground very hot for a short time, having so much moisture around it draws the heat away quickly.

In chemical qualitive analysis, this is known as a flame test.  Many metals (and some non-metals) have distinctive colors.\n\nThe heat of the flame excites one or more electrons of the metal atom causing it to go to a higher energy state.  When the electron returns to the "ground state" electromagnetic energy is released and this appears as light of a specific color.

The length of any metal increases as the temperature rises. \n\nThe increase in length, for the same initial length is different for different metals for the same increase of temperature.\n\nIn bimetallic strips, two metals strips of same length are placed one over the other and are riveted at their ends.\n\nWhen these strips are heated, both strips increase in lengths but one increases more than the other.\n\nBut, as the ends are fixed, to accommodate the increase in length, both bend into arcs of a circle, the less increased strip form the  inner arc and the other form the outer arc.\n\nThis bimetallic strip is in contact with another strip and they are in series with the heating element of the iron. \n\nThis second strip can be depressed at will by means of a screw which can be operated externally.\n\nAs the temperature increases the bimetallic strip begins to bend but it is in contact with the second strip till a particular temperature reaches which is determined by the adjustment of the screw.\n\nWhen that temperature is reached the second strip ceases its contact with the bimetallic strip.

it gets hot, just its not a very good conductor of heat, therefore it cools off basically once the heats removed from it, so when you take it out, its not hot.

Magnesium. Very dangerous around extreme heat as once it is ignited you can not put it out. The military use to cast it for their brakes for their fighter jets because magnesium is so light. However, high speed landings and hot brakes could cause ignition.

It's tranferred to heat/friction from the impact

"Hot" refers to the phrase too "hot" to handle. similar to the expression that car (or anything) is hotter than Hades. One I can't figure is the term rubber check, or bounce unless it refers to the check will bounce back to you because the bank won't honor it. I think I answered my own.  MMMMMMM
