Two glasses are filled with sunflower oil: one at 20 ° C, the other at 60 ° C. What about the internal energy of the oil in the glasses?

The internal energy of a body directly depends on its temperature: the higher the body temperature, the more its internal energy. Since the same substance is poured into glasses – sunflower oil, then the internal energy in the first glass is less, since it has a lower temperature – 20 degrees Celsius.
Therefore, the correct answer is: less in the first glass.
