What happens when a flame heats a metal?
When a flame heats a metal, the metal absorbs the heat energy and its temperature increases. As the metal gets hotter, its atoms vibrate more rapidly, eventually reaching a point where the metal starts to glow and emit light. Continued heating can cause the metal to melt or even ignite if the temperature is high enough.
Is metal a composite material?
Metal is not considered a composite material. It is a type of material that is made up of a single element or alloy. Composite materials, on the other hand, are made up of two or more constituent materials with different properties.
What is the difference between material and metal?
Material refers to any substance that can be used to create goods or products, whereas metal specifically refers to a class of materials that are typically good conductors of electricity and heat, shiny, malleable, and ductile. Metal is a subset of materials, with other examples of materials including plastic, wood, glass, and ceramics.
What metal is unreactive and is not used in pencils?
Gold is a metal that is unreactive and is not used in pencils. Gold's unreactive nature makes it a valuable material for jewelry and other applications where tarnishing or corrosion is undesired.
What melts easily that is a material?
Butter is a material that melts easily. Butter has a low melting point compared to other materials, which allows it to quickly turn from a solid to a liquid state when exposed to heat.

The particular rate at which a material warms up upon absorbing heat is a what property that can be used to identify a substance?
Specific heat capacity is the property that describes the rate at which a material warms up upon absorbing heat. It can be used to identify a substance based on how quickly or slowly it heats up compared to other materials.
Why is metal the best conductor of heat?
Because its electron conduction band is filled with a freely moving "electron gas" that heats up and can move throughout the metal (same as an electric current is a "wind" in this "electron gas"). In other materials the electrons are localized.
Does the sun heats up a pond water fastest?
The sun heats up water at the same rate as any other water. I suppose there would be variations in heat temperature based on the material in the water, such as salt and dirt.
Why didn't they make the statue of liberty out of a different metal?
because the other material is not suitable
Is lead a pure metal?
A pure metal is any metal that has not been alloyed or joined with any other metal or synthetic material. Lead is a pure metal because it is an element and composed of a single kind of atom.
Is lead pure metal?

Are pellets metal?
Air gun pellets are made out of lead or some other soft material.
A material is ductile if it?
can be pulled out or drawn can be hammered or rolled into flat sheets and other shapes can transfer heat or electricity to another material and is a mixture of a metal with at least one other element
What sort of material would conduct electricity?
Any metal, water, skin and many other substances.
What does it mean to make coins?
To produce chips of metal or plastic or any other material that have a given value.
What glue is used to join a metal to another material?
Generally you would use an epoxy or a form of the brand Gorilla Glue. Normally it depends on the other material.
