Question

The melting point of copper is 1084 Celsius. How does the energy of the particles in a certain amount of liquid copper compare to the energy of the molecules in the same amount of liquid water? Why?

Answer 1

The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately {five} times compared to that of water
