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 heat energy is used to melt metal ores and where does it come from?
Heat energy used to melt metal ores comes from various sources such as combustion of fossil fuels like coal or gas, electric resistance heating, or from exothermic chemical reactions. The energy source depends on the specific process and the availability of resources.
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.
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 long will it take to melt a metal with a butane lighter?
The time it takes to melt a metal with a butane lighter will vary depending on the type of metal and the intensity of the heat produced by the lighter. Generally, it would take a significant amount of time and may not be practical to melt metal with just a butane lighter.
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.
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.
How can heat burn through metal?
After the heat source exceeds the melting point of the metal, by nature the metal will melt.
What happens in terms of the transfer of energy as a heat when you hold a snowball in your hands?
When you hold a snowball in your hands, the heat energy produced by your hands is transferred into the fusion of ice to water. Fusion is an endothermic reaction.
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?
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.
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).
Can anything melt a rock?
Substantial heat, whether produced by humans or naturally occurring, can melt rock.
