Air conditioners sold in the United States are given a seasonal energy-efficiency ratio (SEERSEER) rating that consumers can use to compare different models. A SEERSEER rating is the ratio of heat pumped to energy input, similar to a COPCOP but using English units, so a higher SEERSEER rating means a more efficient model. You can determine the COPCOP of an air conditioner by dividing the SEERSEER rating by 3.4. Required:
For typical inside and outside temperatures when you'd be using air conditioning, estimate the theoretical maximum SEER rating if an air conditioner.

Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.
