2. In a full cycle of a heat 3. First Law of Thermodynamics states that the change in the internal energy of the system is equal to the difference between the heat taken in by the system and the work done by the system. How will you describe the change in the internal energy of the system given that the heat taken in is greater than the work done by the system? A. Heat and work have no effect on the internal energy of the system. B. The internal energy of the system changes. C. The internal energy of the system increases as temperature increases. D. The internal energy of the system increases since there is greater amount of heat transferred to the system., there are three events happening; heat is added, some energy from the input heat is used to do work, and lastly, the rest of the heat is removed at cold temperature. If a four-stroke gasoline engine is in operation, how will you describe its efficiency? A. It is 100% efficient because the energy is circulating within a chamber. B. It is not 100% efficient because some of the energy is converted to heat and exhausted to
