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.

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.
Changing the initial mass of the copper will affect the total amount of energy the copper has. More mass means more particles requiring energy for movement and vibration, resulting in a higher total energy. Conversely, less mass will result in lower total energy due to fewer particles needing energy for motion.
Changing the initial temperature of copper will affect the amount of heat energy transferred. A higher initial temperature of copper will result in a greater amount of heat energy being transferred to the surroundings, while a lower initial temperature will result in less heat energy being transferred. This is based on the principles of thermal equilibrium and the heat capacity of copper.

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.

To calculate the energy required to vaporize 2 kg of copper, you need to use the specific latent heat of vaporization for copper, which is approximately 300,000 J/kg. The total energy (Q) can be calculated using the equation Q = m * L, where m is the mass (2 kg) and L is the latent heat of vaporization (300,000 J/kg). Thus, Q = 2 kg * 300,000 J/kg = 600,000 J. Therefore, 600,000 joules of energy is required to vaporize 2 kg of copper.
The temperature of the vaporized gas is significantly higher than the temperature of the solid ice that Yuki began with. When ice melts and then vaporizes, it absorbs heat energy, which raises the temperature of the water and subsequently the vaporized gas. This process involves transitioning from a solid state (ice) at a low temperature to a gaseous state at a much higher temperature, resulting in a considerable increase in thermal energy.
