उत्तर
When heated, an object receives heat from the agency. Now object has more internal energy than before. Heat is the energy in transit and which flows from an object at a higher temperature to an object at a lower temperature. Heat is not a quantity. So the statement I would prefer “an object contains more thermal energy”.
