Quanto calore si deve fornire per aumentare la temperatura di 0,50 kg di ferro da 18 a 50 gradi centigradi

SPECIFIC HEAT  is the amount of heat needed to raise the temperature by one degree

1 gram of substance. Each substance has its own specific heat and if the physical state changes (e.g. liquid, solid, gas)

the specific heat also changes . Units are expressed in Joules per gram per degree Celsius (J / g ° C). Sometimes

the J / kg K unit is also used. The latter unit is technically the most correct unit to use, but since  

since the former is quite common, it is necessary to know both. The specific heat of H2O depending on

phase is indicated in the table.
