If energy cost $1.00 per million joules and the insulation was $4.00 per square meter, then calculate the simple payback time. Take the average T for the 120-day heating season to be 15.0 .arrow_forward
- Energy is the mistress of the Universe, and entropy is her shadow. Writing for an audience of general readers, argue for this statement with at least two examples. Alternatively, argue for the view that entropy is like an executive who instantly determines what will happen, whereas energy is like a bookkeeper telling us how little we can afford. (Arnold Sommerfeld suggested the idea for this question.)arrow_forwardIs it possible for a system to have an entropy change if it neither absorbs nor emits heat during a reversible? transition?
