How much work is done on the gas in the process shown in Figure EX19.1?

Short Answer

Expert verified

The amount of work done energy is80J

Step by step solution

01

Definition of work done

The work done has represented as energy that is transferred between system and environment.

02

Step  2: Finding the work done energy.

In the isobaric process, pressure is negative

Now W=-p鈭�V

V=(Vf-Vi)=(300-100)m3=200cm3

Now convert volume cm to m 2脳10-4m3

So the value of work done is

localid="1651380670133" W=-p鈭�V=(-400脳103脳2脳10-4Pa脳m3)=-80J

0.020mol of a diatomic gas, with initial temperature 20鈭�C, are compressed from 1500cm3 to 500cm3 in a process in which pV2= constant. How much heat energy is added during this process?

The volume of a gas is halved during an adiabatic compression

that increases the pressure by a factor of 2.5.

a. What is the specific heat ratio纬?

b. By what factor does the temperature increase?

A cylindrical copper rod and an iron rod with exactly the same dimensions are welded together end to end. The outside end of the copper rod is held at 100掳C, and the outside end of the iron rod is held at 0掳C. What is the temperature at the midpoint where the rods are joined together?

A 500 g metal sphere is heated to 300C, then dropped into a

beaker containing 300 cm3 of mercury at 20.0C. A short time later

the mercury temperature stabilizes at 99.0C. Identify the metal.

You need to raise the temperature of a gas by 10掳C. To use the least amount of heat energy, should you heat the gas at constant pressure or at constant volume? Explain.
