1. While you are asleep, your body needs to get rid of about 64 J of waste heat every second. The body does this by transferring the heat from the Interior of your body (temperature 37°C) to the skin (temperature 30°C), where it is radiated away. By how much does this heat transfer change the body's entropy each second?
