I need to understand the concept of entropy in thermodynamics. Can you explain it to me in simple terms? Your response should contain at least 3 sentences and less than 10 sentences. Include keywords *thermodynamics*, *disorder*, and *energy* in the response. In your response, the word *entropy* should appear at least 3 times. Your entire response should be in English and in all lowercase letters. no capital letters are allowed. at the end of your response, please explicitly add a postscript starting with p.s.
