Thanks. It's not easy to explain to him but I'll do the best I can. We are discussing about temperature and heat now, but I can see from his eyes that it is a heavy subject for him.

My son is 10 years old and he has questions which many times I can't answer. I don't and honestly can't answer his questions in a simple way that he can understand. Or do I underestimate him? Not so sure about it. His questions are: 1. What is energy and what is its form: is it liquid, solid or gas? 2. What is light? Can somebody help me, please? Thanks.
