What else can I help you with?
How do you make swords?
You can make a "toy" sword from wood by carving the edges down. To make an actual sword from metal, a block of heated metal is pounded, then cooled, then repeatedly heated and flattened again to make it into a hard, narrow strip. This provides strength to the metal. If liquid metal were simply poured into a flat form, it would not have the required toughness.
A heated metal block volume decreases or increases?
It decreases
Which property of a block remains constant when the metal is heated?
Mass
Does metal produce energy when heated?
If you heat metal sufficiently, it will glow, which is an emission of energy, however that energy comes from the heat energy you have added to the metal; the metal itself is not producing energy.
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
When metal is heated the light emitted is because it gains energy as they return to lower energy levels?
Yes, when metal is heated, the atoms in the metal absorb energy and become excited. As they return to their normal energy levels, they release this excess energy in the form of light, which is known as incandescence. This is why heated metal appears to glow.
Does metal expand when heated or cooled?
No. A chemical change occurs only when a new substance is produced with new and different properties. In your example, a physical change occurred because only the metal's physical properties were affected. Nothing new was created.
When metal is cooled by ice what will the particles do?
When metal is cooled by ice, the particles in the metal will slow down and lose kinetic energy, leading to a decrease in temperature. As the metal cools, the particles will eventually reach a point where they freeze and form a solid structure.
Why is metal no longer magnetic when heated?
When heated, the thermal energy supplied to the metal causes the thermal motion of its atoms to increase, disrupting the alignment of their magnetic moments. This disrupts the collective magnetic behavior that gives the metal its magnetic properties. As a result, the metal loses its magnetism when heated.
What could you decrease the thermal energy of a metal block?
You can decrease the thermal energy of a metal block by allowing it to cool in a cooler environment, such as placing it in contact with a cooler surface or exposing it to a colder surrounding. Alternatively, you can reduce its thermal energy by transferring heat away from the metal block through a process like conduction or convection.
What is the Purpose of an enginnering anvil?
It is a heavy block of iron on which heated pieces of metal are made into a particular shape with a hammer
Why does metal change color when heated?
When metal is heated, its atoms vibrate more rapidly and absorb energy. This causes the electrons in the metal to move to higher energy levels, which can change the way they interact with light. This change in electron behavior can result in the metal appearing to change color as different wavelengths of light are reflected.
