You are exercising on a hot day. Your body temperature goes up. You begin to sweat. The sweat cools your body. Sweating is an example of:
input.
process.
output.
feedback.
My answers are b and c.
For the first question, the correct answer is b. The conversion of chemical energy to light energy is a process. This is because it involves the transformation of one form of energy (chemical) into another form (light).
For the second question, the correct answer is process. Sweating is an example of a process because it is a physiological response in the body that involves the release of sweat to cool down. The other options (input, output, and feedback) do not accurately describe the nature of sweating in this context.
