The figure presented illustrates the cyclical process of a refrigerator's operation, in which a gas inside a pipe is forced to circulate between the freezer and the outside of the refrigerator. It is through the processes of compression, which occurs on the outside, and expansion, which occurs on the inside, that the gas provides heat exchange between the inside and outside of the refrigerator. Available at: http://home.howstuffworks.com. Accessed on: October 19, 2008 (adapted). In the energy transformation processes involved in the operation of a refrigerator, A) the expansion of the gas is a process that provides the energy necessary to cool the inside of the refrigerator. B) heat flows non-spontaneously from the colder part, inside, to the warmer part, outside the refrigerator. C) the amount of heat given off to the external environment is equal to the heat removed from the refrigerator. D) efficiency is greater the less thermally insulated its internal compartment is from the external environment. E) the energy removed from the inside can be returned to the refrigerator by opening its door, which reduces its energy consumption. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of ENEM 2009 solutions: 👉   • ENEM 2009 - A invenção da geladeira propor...   Professor Thales Quirino Medeiros ================== #ENEM #physics #medicine #studies #education
