doubt in definition of heat

1 like 0 dislike
According to the books- heat is the energy in transit due to temperature difference between system and surrounding.  
At one time we are saying it is only in transit whereas at next we are saying it flows from high temperature to low temp. i.e from high heat content to low heat content i.e it  refers as heat is stored so these both things are contradicting please help me out

Temperature is not heat content. Temperature refers to the degree of hotness of a body and is a measure of the average internal Kinetic Energy per molecule of the substance.

For exampple,

A bucket of luke warm water has more heat content than a red hot nail. But the red hot nail is at a very high temperature compared to the luke warm water.

that's where the problem lies , according to definition heat cant be contained by a system rather it is something which can only flow,only be in transit  but you used the phrase 'A LUKE WARM WATER HAS MORE HEAT CONTENT' which contradicts the definition
Heat content relates to the total Kinetic Energy of all the molecules according to the Principles of Thermodynamics
