Q.'An object contains more heat' - is it a right statement? If not why?
Step 1. Heat is, by definition, energy in transit that flows only while a temperature difference exists between two bodies; once the flow stops, "heat" no longer describes anything present in the object.
Step 2. Since heat is not a stored quantity (unlike internal energy, mass, or charge), no object can be said to "contain" more or less of it -- exactly as "a lake has more rain" is wrong (rain is a process bringing water; the lake simply "has more water").
Step 3. The physically correct description of a hotter object is that it "is hotter" (referring to temperature) or "has more internal energy" (referring to the actual stored energy), never that it "has more heat".
No, the statement is not correct -- the correct statement is "the object has more internal energy" (or is simply hotter).
