What are the four processes of the Carnot cycle? Sketch the Carnot cycle (a) on T-s (temperature - entropy) and P-V (pressure -
Tanya [424]

Answer:

\eta = 0.7315

Explanation:

Carnot cycle

Carnot cycle have four process

1. Iso thermal expansion

2.Reversible adiabatic expansion

3. Iso thermal compression

4.Reversible adiabatic compression

 This is ideal cycle for all work producing devices.All devices have efficiency less than Carnot cycle. Because in Carnot cycle all process is reversible process.

Efficiency of Carnot cycle given as

\eta =1-\dfrac{T_1}{T_2}

But temperature must be in Kelvin

So

\eta =1-\dfrac{288}{1073}

\eta = 0.7315

Your study space does not need to be quiet as long as you can ignore any noise coming from the space true or false?
Makovka662 [10]

Answer:

False

Explanation:

When you're studying, you need to make sure that you can focus properly. This means that you shouldn't be hungry or too full and that you should be well-rested, in a quiet room with good lighting and no distractions. Noise is never good when you need to memorize something. Some people can partially ignore it as long as it isn't too loud, but it will begin to bother them eventually. That's why it's better to study in a quiet room.
