You put heat energy into your car and it does not work . The difference between what you put in and the work it does is the change in internal energy of your car's "system." This is an example of which law of thermodynamics?

Many thermodynamic processes occur naturally in one specific direction but not in the opposite direction. For instance, cooling a closed environment on a very hot day requires electrical energy to be carried out, as in the case of an air conditioner. Why is that? Another example: it's easy to fully convert mechanical energy into heat, which happens every time we use the brakes to stop a car. However, in the opposite direction, there are many devices that only partially convert heat into mechanical energy, like the engine of a car. But even the most talented inventor has yet to build a machine capable of fully converting an amount of heat into mechanical energy. Once again, why? The answer to these two questions is related to the directions of thermodynamic processes and is provided by the second law of thermodynamics.   With regard to various concepts related to the Second Law of Thermodynamics, analyze the following statements: Thermal machines are devices used to convert mechanical…

A hollow drinking straw is placed in a glass of warm water.  Suppose that some of the water started to climb to the top of the straw and cooled down so that the increase in potential energy was balanced by a loss of heat.  Which law of thermodynamics forbids this from happening? (A) The 0th law (B) The 1st law (C) The 2nd law (D) The 3rd law

Which one of the following statements about an ideal gas is true? During an isochoric process, the change in internal energy of the gas is exactly equal to the amount of heat flow into or out of the gas During an isothermal process, the entropy of the gas does not change. During an isothermal process, no heat enters or leaves the gas. During an adiabatic process, the temperature of the gas does not change. During an isobaric process, no work is done on or by the gas. oooo
