AQA Science Exam Question and Answer
Question:
In the context of energy transfer, what does "cool" refer to, and how does it relate to thermal energy?
Answer:
In the context of energy transfer, "cool" refers to the process of losing thermal energy or decreasing in temperature. When an object cools down, its atoms and molecules slow down, reducing their kinetic energy, and causing the object to feel colder. This cooling process occurs when thermal energy is transferred from the object to its surroundings, either through conduction, convection, or radiation.
