Question

can some one help me out? I can't chose between A or B
If an increase in temperature accompanies a reaction, what occurred?




Energy was absorbed.



Energy was released.



Energy was destroyed.



Energy was created.

I don't think its C but then again I could be wrong

  • Answer : If an increase in temperature accompanies a reaction, energy is released. Explanation :In thermodynamics, the reaction is considered as a system and the medium in which the reaction occurs which is usually an aqueous medium is considered as its surrounding. When the heat flows from the system to its surrounding, it increases the temperature of surrounding medium because the heat released by the system is absorbed by its surrounding. This is known as exothermic reaction. An exothermic reaction is always accompanied by energy release. On the other hand, when the heat flows from the surrounding towards system, it decreases the temperature of the surrounding medium. This is known as endothermic reaction. From the above discussion we can say that If an increase in temperature accompanies a reaction, energy is released.

    Good luck ;)

  • A. Energy was absorbed.

    When particles are heated, they to start moving around more, which means they have more kinetic energy. (If it's an object's temperature that's increasing)
