The engine of a Ferrari F355 F1 sports car takes in air at 20°C and 1 atm and compresses it adiabatically to 0.09 times the original volume. The air may be treated as an ideal gas with γ=1.4 . (a) Draw a pV-diagram for this process. (b) Find the final temperature and pressure.

Short Answer

Expert verified

a.

b. The final temperature ans pressure is T2=768Kand P2=29atmrespectively.

Step by step solution

01

Draw the pV diagram of the process

For the adiabatic compression process, the volume decreases while the pressure increases. The graph will be as follows

02

Calculate the final temperature

For an adiabatic process, the relation between temperature and volume isT1V1γ-1=T2V2γ-1and between pressure and volume is P1V1γ=P2V2γ .

Here, v1and v2is the initial and final volume respectively. Next T1 and T2 is the initial and final temperature respectively. And P1 and P2 is the initial and final pressure respectively.

Consider the given data as below.

V2=0.09V1.

Define the final temperature as below.

T2=T1V1V2γ-1=293V10.09V114-1=768K

03

Calculate the final pressure

Define the final pressure as below.

P2=P1V1V2γ=1×V10.09V114=29atm

04

Result:

The final temperature and pressure isT2=768K and P2=29atm respectively.

On a sunny day, large “bubbles” of air form on the sun-warmed earth, gradually expand, and finally break free to rise through the atmosphere. Soaring birds and glider pilots are fond of using these “thermals” to gain altitude easily. This expansion is essentially an adiabatic process. Why?

Imagine a special air filter placed in a window of a house. The tiny holes in the filter allow only air molecules moving faster than a certain speed to exit the house, and allow only air molecules moving slower than that speed to enter the house from outside. Explain why such an air filter would cool the house, and why the second law of thermodynamics makes building such a filter an impossible task.

A rigid, perfectly insulated container has a membrane dividing its volume in half. One side contains a gas at an absolute temperature and pressure , while the other half is completely empty. Suddenly a small hole develops in the membrane, allowing the gas to leak out into the other half until it eventually occupies twice its original volume. In terms of and , what will be the new temperature and pressure of the gas when it is distributed equally in both halves of the container? Explain your reasoning.

A constant-volume gas thermometer registers an absolute pressure corresponding to 325 mm of mercury when in contact with water at the triple point. What pressure does it read when in contact with water at the normal boiling point?

In a constant-volume process, dU = nCV dT. But in a constant-pressure process, it is not true that dU = nCp dT. Why not?
