The heat capacity is defined as the amount of energy required to change the temperature of an object. The specific heat capacity is defined as the amount of energy required to change the temperature of an object per mole of the substance.
a) Heat capacity is an Intensive quantity Extensive quantity
b) Specific heat capacity is an Intensive quantity Extensive quantity
A human being (75 kg ) consumes about 6000 Kj of food per day. Assume that the food is all glucose and that overall reaction is- C6H12O6 +6O2 ------à 6CO2 +6H20 , Δ H= -2816 KJ
