Where did heat energy used to melt metal ores come from?
Heat energy used to melt metal ores typically comes from burning fuels such as coal, oil, or natural gas in a process called smelting. The fuel provides the necessary heat to raise the temperature of the ore to its melting point, allowing the metal to be extracted from the ore.
What produced the heat energy used to melt metal ores?
The heat energy used to melt metal ores is typically produced by burning fuel such as coal, natural gas, or charcoal in a furnace. The combustion of these fuels generates high temperatures that are necessary to melt the metal ores.
Where does the energy needed to melt the iron come from?
The energy needed to melt iron typically comes from heating the iron to its melting point, which requires input of heat energy. This heat energy can be created by burning fuels, using electric resistance, or other heat sources that can raise the temperature of the iron to the point where it transitions from a solid to a liquid state.
How does metal react to heat?
When metal is heated, the kinetic energy of its atoms increases, causing them to vibrate more rapidly. As the temperature rises, the metal expands due to thermal expansion. Eventually, at high enough temperatures, the metal may begin to melt and change its physical state.
What is the measurement of how much heat energy is required for a substance to melt?
The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.

Why wont microwaves melt metal?
Although metal can get very hot a microwave does not produce enough energy to heat most metals to their melting points.
How can heat burn through metal?
After the heat source exceeds the melting point of the metal, by nature the metal will melt.
Does ice melt faster on metal or plastic?
Ice melts faster on metal because metal is a good conductor of heat, allowing heat energy to transfer quickly to the ice. Plastic is a poor conductor of heat, so it retains heat better and slows down the melting process of ice.
Where does heat come from to melt metal ores?
Heat to melt metal ores typically comes from burning fuels such as coal, natural gas, or wood in a furnace. The heat generated from the combustion of these fuels is directed towards the metal ore in order to reach its melting point. Other sources of heat could include electricity in the form of an electric arc furnace.
Does electrocution really melt silver?
If enough electrical energy is put into a metal, it can easily melt that metal.
How does metal react to heat?

What metal is a liquid at room temperatrue?
Mercury is the only metal liquid at room temperature. Others come close, like Gallium, which will melt in your hand from body heat.
Why is heat energy needed to melt a solid what is heat energy called?
Heat energy is needed to melt a solid because it increases the kinetic energy of the particles, causing them to break free from their fixed positions in the solid structure. The heat energy required to melt a solid is called "latent heat of fusion."
Why is heat energy needed to melt a solid what is this heat energy called?
This energy is the enthalpy of fusion (or latent heat of fusion).
