O.385x1x2=0.77 Answer: 0.77
It would be solid... Copper's melting point is as high as 1,084 C
Copper is a solid at 2000 degrees Celsius. It has a melting point of 1084 degrees Celsius, so at 2000 degrees Celsius, copper would be in its liquid state.
The specific heat capacity of copper is about 0.385 J/g°C. To find the total heat energy needed to heat 1 kg of copper by 2°C, you can use the formula: Q = m * c * ΔT Where: Q = heat energy m = mass (1 kg) c = specific heat capacity (0.385 J/g°C) ΔT = change in temperature (2°C) Plugging in the values: Q = 1 kg * 0.385 J/g°C * 2°C = 0.77 kJ Therefore, 0.77 kJ of heat energy would be needed.
To prepare a saturated solution of copper sulfate at 20 degrees Celsius, you would need to dissolve approximately 203 grams of copper sulfate in 400 grams of water. This is based on the solubility of copper sulfate in water at that temperature.
Solid
The specific heat capacity of copper is approximately 0.385 J/g°C. Therefore, to raise the temperature of 1 kg (1000 g) of copper by 1°C, you would need 385 J of thermal energy.
I thought I answered this. As I said before, I am too lazy to look up the specific heat of copper (google it ) and I assume the temperature initial is the standard 25 Celsius. Here is the set-up. q(amount of energy in Joules ) = ( 50g Copper)(specific heat of copper in J/gC )(55C-25C)
Thermal energy is a measure of the internal energy of a system and is not dependent on the unit of temperature used. Therefore, the thermal energy at 0 degrees Celsius would be the same as at 48 degrees Fahrenheit.
To melt 10 grams of ice at 0 degrees Celsius, it would require 80 calories of heat energy per gram, so a total of 800 calories (80 calories/gram * 10 grams = 800 calories) would be needed.
Copper penny
Supply for copper from outside will decline, Demand for copper locally will increase. More labour needed.
No, pennies are made of mostly zinc with a thin copper coating. The melting point of copper is higher than the temperature needed to melt a penny, so the outer copper layer would simply burn off if heated to that extent. Additionally, it is illegal in the US to destroy or deface currency.
