If the container becomes hot during a reaction, which conclusion is most suitable?
Answer and explanation
Correct answer: Heat has been released
A container becoming hot indicates that energy is being transferred from the reacting system to its surroundings. This is evidence that heat has been released and the reaction is likely exothermic, so option C is correct. However, the observation alone does not prove combustion; other exothermic reactions can also warm the container. It also does not represent mere state change or absence of reaction.
