Question

Assume the air in a room is a perfect diatomic gas. You come into the room one day and find the temperature is 20 degree C. You turn up the thermostat, and 45 minutes later the temperature has risen to 25 degree C. Has the internal energy of the air in the room increased, decreased or remained essentially the same? Defend your choice qualitatively and quantitatively using concepts and relations from Chapter 18 and 19(Temperature, Heat and the First Law of Thermodynamics and The Kinetic Theory of Gases)..Please explain answer in thorough and gory detail since this is worth a lot of points..Thank You

Explanation / Answer

it will increase just because there is some work has to be done either to icrease the temperature or to decrease the temperature....since this work is done by thermostat and from thermostat principle they never supply the energy from outside process....so if from conservation of energy of temperature is risen then internal energu has to increase.
