Chapter 3: Q8DQ (page 609)

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.

Short Answer

Expert verified

Thetemperaturewill be same

The pressure will be halved

Step by step solution

01

Determine the ideal gas Equation

Equation for Ideal Gas is

02

Step 2:Determine the new temperature and pressure of the gas when it is distributed equally in both halves

When the gas move from one side to other and its volume is doubled apply the ideal gas law

the gas move from one side to other Ha s the same R and Number of moles

when the molecules move there will be nofrictionorincreasein thetemperaturedue to moving and the movement depend only on the velocity and mass othe the molecules where the kinetic energy equals

Therefore ,thetemperaturewill be same

By keeptemperaturesame and double the volume we will have the half of the pressure asvolumeis inverselyproportionalto pressure

So after moving The pressure will behalved

Therefore The pressure will be halved

When a wet cloth is hung up in a hot wind in the desert, it is cooled by evaporation to a temperature that may be20C°or so below that of the air. Discuss this process in light of the second law of thermodynamics.

Question: If the air temperature is the same as the temperature of your skin (about 30°C), your body cannot get rid of heat by transferring it to the air. In that case, it gets rid of the heat by evaporating water (sweat). During bicycling, a typical 70-kg person’s body produces energy at a rate of about 500W due to metabolism, 80% of which is converted to heat. (a) How many kilograms of water must the person’s body evaporate in an hour to get rid of this heat? The heat of vaporization of water at body temperature is 2.42×106J/kg. (b) The evaporated water must, of course, be replenished, or the person will dehydrate. How many 750-mL bottles of water must the bicyclist drink per hour to replenish the lost water? (Recall that the mass of a litre of water is 1.0 kg.

Is it a violation of the second law of thermodynamics to convert mechanical energy completely into heat? To convert heat completely into work? Explain your answers.

Comment on the following statement:When two gases are mixed, if they are to be in thermal equilibrium, they must have the same average molecular speed.Is the statement correct? Why or why not?

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?
