A system's "entropy" is
(a) the amount of work the system can do.
(b) the amount of microscopic work the system can do.
(c) the amount of force the system could exert.
(d) the amount of thermal energy in the system.
(e) the amount of microscopic disorganization in the system.
A bit of computer memory is some physical object that can be in two different states, often interpreted as 0 and 1. A byte is eight bits, a kilobyte is 1024 (= 210) bytes, a megabyte is 1024 kilobytes, and a gigabyte is 1024 megabytes.
If this entropy is dumped into an environment at room temperature, how much heat must come along with it? Is this amount of heat significant?
Your last exam is done and you have a two week break before the next semester starts. You look around and see that your room is a mess. You haven't had the time to pick up after yourself the last few days. As you start putting all your stuff in their proper places you wonder,
"Am I not creating order from disorder? Didn't the Second Law of Thermodynamics just tell me that any process that reduces the Entropy (Disorder) of the Universe is forbidden? But I create order from disorder every time I clean my room!"
Did you just break the Second Law of Thermodynamics or can you explain why your actions (cleaning your room) does not violate the Second Law? Argue your case is a few sentences.
