Acup containing 200 g of hot water is taken off the stove placed on the kitchen table. initially the water is at 75degree c. but it cools down spontaneously and comes to equilibrium with the room at 21 c. the process takes places at constant pressure. what are delta h, q, and delta s for the water? what is delta s_surrounding? what is delta s_universe? take cp = 4. 184 j/(mole. k) for water and assume that this is approximately constant over temperature range of interest.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
