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.
To calculate the heat energy required, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass of the copper (0.365 kg), c is the specific heat capacity of copper (0.0920 J/g°C), and ΔT is the change in temperature (60.0°C - 23.0°C). First, convert the mass to grams and then plug the values into the formula to find the heat energy required.

To vaporize 1 ounce (approximately 28.35 grams) of copper, you would need about 1,800 joules of energy per gram, as the heat of vaporization of copper is around 1,800 kJ/kg. Therefore, the total energy required for 1 ounce of copper would be approximately 51 kJ (or 51,000 joules). This calculation assumes that the copper is initially at its melting point before vaporization occurs.

The amount of heat energy required can be calculated using the formula: Q = mcΔT. Given m = 0.362 kg, c = 390 J/kg°C for copper, and ΔT = (60.0 - 23.0) = 37.0 °C, plug these values into the formula to find the heat energy required to raise the temperature of the copper.
Basketball was developed out of a desire for a vigorous sport. why was there a desire for a sport that required so-much energy?
Aluminum is much lighter than copper and has a lower conductivity which makes it easier for it to create more force. It is also much cheaper than copper.

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.
