To melt copper, approximately 1,200 BTUs (British Thermal Units) are required for each pound of copper. This value accounts for both the heat needed to raise the temperature of the copper to its melting point (about 1,984°F or 1,085°C) and the latent heat of fusion. The exact amount can vary slightly based on the specific conditions and purity of the copper.
The fusing current is a value of current that causes the fuse to melt and interrupt the flow of current. Usually, reference is made to the minimum fusing current which is the smallest value of current that will cause the fuse to melt.
You cant it is physically impossible without a machine
a fuse
The windings melt. Also may start a fire if surround conditions permit.
Good question. There are a few simple answers. Most solders begin to become "plastic" at around 350 degrees Fahrenheit and melt at slightly higher temperatures than even that. If you are asking about a hot water heater: If you are operating your water heating system at that temperature the water will have already boiled off and most likely the heater will either have exploded, the P/T relief valve dumped or both. If you are asking about an electric heater, do not try to melt solder on it. The heating element is electrically "hot" and could present an extreme shock hazard. The best way to melt solder is with with a soldering iron or some kind of torch. Hope this helps
The energy required to melt 1 kg of copper at its melting point of about 1084°C is approximately 205 kJ. Therefore, to melt 2 kg of copper, you would need around 410 kJ of energy.
No, wood cannot be used to melt copper because the temperature required to melt copper (1,984°F or 1,085°C) is much higher than the ignition point of wood (around 572°F or 300°C). To melt copper, a heat source such as a furnace or a torch that can reach the required temperature must be used.
From high school science class; it takes 144 BTUs to melt a pound of ice. That takes it to 32 degrees F. To then raise the temp to 72 deg., would take about 40 more BTUs.
To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
To change 5 pounds of ice at 20°F to steam at 220°F, you will need to go through multiple phases: raise ice temperature to 32°F, melt ice to water at 32°F, raise water temperature to 212°F, and then convert water to steam at 212°F to steam at 220°F. The total heat required, in BTUs, is around 503 BTUs per pound of ice, which translates to about 2515 BTUs for 5 pounds of ice.
If 12,000 btuh = 1 ton cooling = 2000 pounds ice; then 12 btuh will melt 2 pounds of ice to water.
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.

To calculate the heat required to melt 3 x 10² kg of copper, we use the formula ( Q = m \cdot L_f ), where ( Q ) is the heat, ( m ) is the mass, and ( L_f ) is the latent heat of fusion for copper, which is approximately 200 kJ/kg. For 3 x 10² kg of copper, the heat required would be ( Q = 3 \times 10² , \text{kg} \times 200 , \text{kJ/kg} = 60,000 , \text{kJ} ). Thus, it takes about 60,000 kJ of heat to melt that amount of copper.
It is possible to melt metals including copper. It requires a very high level of heat, depending on the metal.ADDED@ Not sure why that "and copper". Copper IS a metal.
The use of fire, likely from pre-existing campfires, was probably the primary method used by Homo sapiens to melt copper for shaping into tools or ornaments. This would have required the ability to control and maintain a high enough temperature for the copper to melt and be molded into desired shapes.
To calculate the amount of BTUs required to melt 1 ton (2000 pounds) of steel in 1 hour, we need to consider the specific heat capacity of steel, which is approximately 0.11 BTU/lb°F. The melting point of steel is around 2500°F. Assuming the steel starts at room temperature (70°F), it would take approximately 2,200,000 BTUs to melt 1 ton of steel in 1 hour [(2500°F - 70°F) * 2000 lbs * 0.11 BTU/lb°F].
