    the First Law of Thermodynamics but not the Second Law of Thermodynamics.

    b.

    the Second Law but not the First Law.

    c.

    both the First Law and the Second Law.

    d.

    neither the First Law nor the Second Law.

Answer #1

First law of thermodynamics states that heat and work are mutually convertible, and creation of energy from nothing can be achievable and doesnot specify the direction of heat and work

Second law of thermodynamics(clausius statement) states that heat cannot flow from a body at lower temperature to another body at higher tempertaure without the aid of the external energy

So the above statement clearly contradicts the Clausius statement of tranfer of energy. Therefore the above statement violates the second law but not the first law because in the second law they specified about the direction of flow of heat is from lower body and the first law doesnot specify anything regarding direction of flow of heat.

Hence the option is B.Second law but not the first law

The hot reservoir for a Carnot engine has a temperature of 933 K, while the cold reservoir has a temperature of 326 K. The heat input for this engine is 7160 J. The 326-K reservoir also serves as the hot reservoir for a second Carnot engine. This second engine uses the rejected heat of the first engine as input and extracts additional work from it. The rejected heat from the second engine goes into a reservoir that has a temperature...

We have a Carnot engine operating between a hot reservoir A and a cold reservoir B. The work produced in the engine is used to power a flywheel. The hot reservoir is boiling water at p0 = 1 bar and Ta = 373K. The cold reservoir is a block of ice at p0 and Tb = 273K (latent heat = 3.3E5 J/kg). For the flywheel we know that Inertiamoment = 2kg m^2, mass = 6kg, c = 418J/kg K. Final...

A parallel flow heat exchanger is used to transfer heat from hot water at 80oC, flowing at 5 L/min to cold water at 15oC which is flowing at a rate of 15 L/min. The overall heat transfer coefficient is 2000 W/m2oC and the area is 0.2m2. Calculate the heat transfer rate, the outlet temperature of the cold water.

Consider three engines that each use 1650 J of heat from a hot resevoir (temperature = 550 K). These three engines reject heat to a cold resevoir (temperature 330 K). Engine I rejects 1380 J of heat. Engine II rejects 990 J of heat. Engine III rejects 785 J of heat. One of the engines operates reversibly, and two operate irreversibly. However, of the two irreversible engines, one violates the second law of thermodynamics and could not exist. What is...

Heat in the amount of 150 KJ is tranferred directly from a hot reservoir at Th = 550k to two cooler reservoirs at T1 = 350k and T2 = 250k. The surrounding temperatures is TS = 300K. If the heat transferred to the reservoir at T1 is half that tranferred to the reservoir at T2, calculate: a. the entropy generation in KJ / K b. the lost work **Please show me the formula and steps how to do this problem...
