Aclosed, rigid tank fitted with a paddle wheel contains 2 kg of air, initially at 300 k. during an interval of 5 minutes, the paddle wheel transfers energy to the air at a rate of 1 kw. during the interval, the air also receives energy by heat transfer at a rate of .5 kw. these are the only energy transfers. assuming the ideal gas model for the air, and no overall changes in kinetic or potential energy, determine the final temperature of the air, in k.
