quanityt of heat (1 Viewer)

[ronaldinho]

copper and water both of 100 degrees celcius and mass of 200g is placed in water of 100 g and 25 degrees celcius..

why is it that the 200 g of water heats the water more than the copper..

plz give a detailed answer if possible

Temperature is a measure of all the vibrational kinetic energy contained within a substance. Due to the strong intermolecular forces between the individual water molecules (hydrogen bonding), it requires a lot of energy to make the molecules vibrate. This results in water's high specific heat capacity of 4.18 j / g / K. Copper's specific heat capacity is much lower. More energy input is required to heat water to 100 degrees than copper. Hence the energy contained within the vibrational kinetic energy of the water is greater than the energy within the copper. This temperature is lost through conduction until the temperature is uniform throughout the whole system. As the 100g of copper contains less energy, it will not heat the water as much.
