If you visited mount shasta city (elevation 900 m [3000 ft.]) and found the outside air temperature to be 27°c (81°f), what would be the air temperature at the summit of mount shasta (elevation 4200 m [14,000 ft.]) at that moment-assuming that the temperature conditions with altitude change at an average, or normal, lapse rate?

If 0.05j work is done by stirring a cup of tea, if 150ml of tea is stirred 50 times and temperature rises to 67c° what will be the increase in entropy? a)0.007j/k b)1.1j/k
