But the second one is output.
Ok, so what might be feedback?
a b b d d is the answers
Your answers are correct!
In the first question, the chemical reaction in the batteries that converts chemical energy to light energy is an example of a process. Therefore, option b - "The conversion of chemical energy to light energy is a process" - is the correct answer.
In the second question, sweating is an example of a process. Sweating helps cool down the body by evaporating from the skin's surface, thus removing excess heat from the body. Therefore, option b - "process" - is the correct answer.
