A body's temperature is observed to increase by K Does this mean heat has been added to the body?
Not necessarily: work could have been done on the body, and that could lead to an increase in the temperature without any heat exchange.
Meaningless question: heat has no precise scientific definition.
No: heat is transferred only when hot matter is added to cooler matter.
Yes: the body got hotter, so heat must have been added to the body.
