An iron piece get heated faster than water even though same amount of heat energy is applied in both.why?
Specific heat capacity is a property of materials which gives how much energy must be added to a unit mass of a specific material to increase it's temperature by 1 degree Kelvin.
According to The engineering toolbox , water has a specific heat capacity of
This means that in order to raise the temperature by 1 degree Kelvin of 1 kg of water, 4187 joules must be transferred to the water.
For iron, only 450 joules need to be transferred to raise 1kg of Iron by 1 degree Kelvin.
Hence if we were to transfer 450 Joules to Both 1kg of Iron and 1kg of water, the Iron would heat up by 1 degree, but the water would only heat up by about
