Question

When a 3-kg iron skillet is heated on the stove, it becomes hot very quickly. When 3 kg of water is heated on the stove it heats up slowly. What is the reason for this difference?

Answer 1

the difference is due to water's capacity to absorb heat energy without undergoing the kind of temp increases that you would find with say metals.

this happens because water molecules are polarised - each molecule of H2O has a plus and a minus charge due to retricemetric charge distribution. and thus H2O molecules behave almost like little magnets. when heated, the average distance between molecules increases and thus energy is stored in the electric field between them as potential energy. the speed at which the molecules are vibrating will also increase but at a rate much less than for say a metal.

in a metal [pretty much] all the energy goes into vibrations of ions which we experience and measure as heat, the kinetic energy of these vibrations equalling the heat energy added.

Answer 2

"retricemetric "

*asymmetric*

Answer 3

another explanation is that
in iron because it is a solid due to which the seperation between pthe seperation between particles is very less then liquids
when heat is added the particles of the both mediums viberates at very high speed which enables them to transfer heat so the rate of transfer of heat is quicker in iron then water
