Imagine the following scenario: a metallic cube of temperature ti, sitting on a horizontal surface, is being heated with a heat gun aimed vertically down on its top surface. after some time has passed, the temperature of the cube is measured to be higher: t2> ti. with no external force applied, the cube suddenly accelerates along the surface out from under the heat gun. after traveling some distance d, it slows and stops, and its temperature is measured again and is shown to have decreased to t3, such that ti t3 t2. what physical law is definitely violated in this scenario? 0 a. conservation of mechanical energy ob. conservation of total energy 0 c. the first law of thermodynamics d. the second law of thermodynamics
