Chapter 19: Q. 9 (page 543)

Draw a first-law bar chart (see Figure 19.12) for the gas process in Figure EX19.9

Short Answer

Expert verified

The work done and heat is same magnitude but heat is positive and work done is negative

Step by step solution

01

Definition of isothermal process 

Isothermal process that the temperature remain constant due to change of process

02

Finding the major points of the diagram

Based of the graph, the volume increase and energy decrease due to transfer from system to environment.

As temperature is constant the value of work done and heat is same but work done sign is negative and heat is positive.

A beaker with a metal bottom is filled with 20gof water at 20°C. It is brought into good thermal contact with a 4000cm3container holding 0.40molof a monatomic gas at 10atmpressure. Both containers are well insulated from their surroundings.

What is the gas pressure after a long time has elapsed? You can assume that the containers themselves are nearly massless and do not affect the outcome.

What is the maximum mass of ethyl alcohol you could boil with 1000 J of heat, starting from 20C?
