Which of the following phrases can describe an endothermic process?

A. A system gives off energy as it cools down.
B. Energy is released in forming the bonds of the product molecules in a reaction.
C. The net energy change for a reaction is positive.
D. Energy is transferred to the surroundings by either heat or work.

is the answer c.

I agree.

Yes, c is correct.

No, the answer is not C. The correct answer is A. A system gives off energy as it cools down. An endothermic process is a process or reaction that absorbs or takes in heat energy from its surroundings. Therefore, when a system undergoes an endothermic process, it gives off energy as it cools down.

No, the answer is not C. The phrase that can describe an endothermic process is A.

An endothermic process is one in which energy is absorbed from the surrounding environment. This means that the system gains energy, typically in the form of heat, from the surroundings. In the given options, phrase A describes an endothermic process as it states that "a system gives off energy as it cools down". When a system cools down, it releases heat energy to its surroundings, indicating an endothermic process.
