What is the relation between the work done for this cycle if b->c is an adiabat vs if b->c is an isotherm?

One mole of an ideal gas is used as the working substance of an engine operating in the cycle shown in the figure below. BC and DA processes are reversible adiabatic.a) Is the gas monoatomic, diatomic or triatomic?b) What is the efficiency and engine?

A monatomic gas is take through a cycle from A to B to C and back to A. At A the pressure is 100,000 pa, the volume is 4.0 liters, and the temperature is 300K. The gas is compressed adiabatically until the volume is 1.0 liters (at B). How much energy was given to or removed from the gas during the adiabatic process?

A certain gasoline engine is modeled as a monatomic ideal gas undergoing an Otto cycle, represented by the p-V diagram shown in the figure. The initial pressure, volume, and temperature are p1 = 1.05 × 105 Pa, V1 = 0.035 m3, and T1 = 290 K, respectively. a)The first step in the Otto cycle is adiabatic compression. Enter an expression for the work performed on the gas during the first step, in terms of V1, V2, and p1.  b) Calculate the temperature of the gas, in kelvins, at the end of the first step.  c)The fourth and last step in the Otto cycle is isochoric cooling to the initial conditions. Find the amount of heat, in joules, that is discharged by the gas during the fourth step.

Suppose a heat engine design makes a square on a PV diagram, using a monatomic gas. The high pressure is 3P and low pressure is P. The high volume is 3V and low volume is V. What is the efficiency of the heat engine?

In one cycle a heat engine absorbs 520 J from a high-temperature reservoir and expels 310 J to a low-temperature reservoir. If the efficiency of this engine is 57% of the efficiency of a Carnot engine, what is the ratio of the low temperature to the high temperature in the Carnot engine? Tlow Thigh  =

The team is playing around with some Carnot cycle numbers. For each transformation, we have the following: (a) Isothermal expansion: 25,338 J (b) Adiabatic expansion: 33,097 J (c) Isothermal compression: 23,182 J (d) Adiabatic compression: 27,995 J Answer the following: 1) Total change in heat within this parcel after one complete cycle. 2) What is the efficiency of the cycle?

Steam locomotives have an efficiency of 15.0% and operate with a hot steam temperature of 475°C. (a) What would the cold reservoir temperature (in °C) be if this were a Carnot engine? °C (b) What would the maximum efficiency of this steam engine be if its cold reservoir temperature were 150°C? % Additional Materials B Reading ds Scanned with CamScanner
