A nail made of iron and a bowl of water have the same temperature because they are on the same table for long time. You transfer heat to them, so the internal energy of each doubles, then... the water will have the higher temperature. the iron will have the higher temperature. both will have the same temperature.

What is the change in internal energy () of a system when it does 27 J of work while absorbing 34 J of heat?
How much heat, in joules, is transferred into a system when its internal energy decreases by 165 J while it was performing 29.5 J of work? Q = - 189.51
Heat always flows spontaneously from an object with a higher temperature to an object with a lower temperature. Is this the same thing as saying that heat always flows from an object with a greater internal energy to one with a lower internal energy? Explain.
Is it possible to convert internal energy to mechanical energy? Explain with examples.
Warm winds called Chinooks sweep across the plains ju Mountains. These winds carry air from high in the mountain rapidly enough that the air has no time to exchange heat with a particular Chinook day, temperature and pressure high in the 60 kPa and 265 K, respectively; the plain below is 90 kPa. (a) the plain, does its volume increase or decrease? (b) How about And its internal energy? Please give explanations for all your answers
If I bring a small object at temperature 200C in thermal contact with a large object at the same temperature, a) thermal energy will flow from the large to the small object because the large object has more internal energy. b) thermal energy will flow from the small to the large object because that will increase entropy. c) thermal energy will not flow.
