A child opens the door of the freezer that is turned off, to observe its operation. If the ambient temperature is 30°, what will be the behavior of the internal temperature of the freezer when it is opened and why? a. does not change, since there is no material between the environment and the interior of the freezer for heat exchange b. is increasing, because the convection between the environment and the air inside the refrigerator does not transfer heat from the outside to the center c. does not change, since there is no contact between the surface of the meat and the external environment d. increases, because sunlight falls on the meat, increasing the energy. Then, when turning on the freezer again, it is observed that the back of the freezer gradually warms up, and remains warm during the operation of the machine. The amount of thermal energy emitted by the freezer must be: a. equal to 0; the heating is due to a problem with the freezer b. Less than the energy drawn from inside the freezer to cool it c. Equal to the energy extracted from the interior of the freezer to cool it d. Greater than the energy drawn from the inside of the freezer to cool it
