Answer to Question #116915 in Molecular Physics | Thermodynamics for jack

Question

Umar has two pans, each containing 500cm3 of water. Pan 1 is made from copper and pan 2 is made from iron. Both have a mass of 1.5kg. Which pan will require more energy to heat the water to 100°C?

Answer 1

The specific heat of iron is 0.450 J/g°C and The specific heat of copper is 0.385 J/g°C

As E=mc$\Delta$T hence more the value of c more is the heat required to achieve the same temperature

as 'c' of of iron being greater than copper hence it will require more heat to achieve that temperature
