An engine does 10 ] of work however, it requires 100 ] of heat to do that work. What is the engine's efficiency? O 1% 10% O 100% O 1,000% Question 2 10 pts An engine has a hot reservoir at 100 ] and a cold reservoir at 50 J. What is the engine's efficiency? 20% O 50% O 100% O 150%A Carnot engine 0 Is a hypothetical heat engine. 0 operates on a reversible cycle. 0 transforms heat Into mechanical energy. D All are correct. Which of the following violates the Second Law of Thermodynamics? C) An Ice cube melting in a glass of water 0 A cup of room-temperature water spontaneously freezing O Water boiling at 3?3 Kelvin 0 Water freezing at 273 Kelvin Entropy is the measure of O disorder O work done O heat transferred O energy transferred Question 6 10 pts Which of the following statements correctly describe a heat engine? O Heat engines transform heat into work O Heat engines transform work into heat O All heat engines are 100% efficient O Heat engines transfer no heat to the environmentQuestion 7 10 pts What is the efficiency of a heat engine whose ignition transfers 3.25 x 103 ] into the system and the exhaust transfers 2.32 x 105 ] out of the system? O 10% O 12% O 29% O 43% Question 8 10 pts The Carnot engine shows that the efficiency of a heat engine is related to O the volume of a fuel tank in an engine. O the amount of coal a steam engine can burn. O the high and low temperatures under which the engine operates.Question 9 10 pts Which of the following systems has high entropy? O A clean and organized bedroom O A neatly stacked tower of building blocks O An organized shelf of DVDS O Pencil shavings scattered across a desk Question 10 10 pts Calculate the efficiency of a heat engine whose ignition transfers 5.75 x 104 J into the system and the exhaust transfers 3.24 x 104 J out of the system.
