Instead of Styrofoam, you try taking a metal cooler to the water park. This cooler has a surface area of 1.5 meters squared, has walls 0.02 meters thick, but the metal material has a thermal conductivity of 50 . The temperature inside the cooler starts at 5 Celsius, and the temperature outside is 38 Celsius.
Calculate the heat energy per second lost by the cooler.
◯ 142.500 joules per second.
◯ 3.33 joules per second.
◯ 22. Jouies per second
◯ It is impossible to calculate.
◯ 123,750 joules per second.
