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 5.0-m-diameter garden pond is 30 cm deep. Solar energy is incident on the pond at an average rate of 400 W/m2 . If the water absorbs all the solar energy and does not exchange energy with its surroundings, how many hours will it take to warm from 15掳C to 25掳C?

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.

A rapidly spinning paddle wheel raises the temperature of 200 mL of water from 21掳C to 25掳C. How much

(a) heat is transferred and

(b) work is done in this process?

You would like to put a solar hot water system on your roof, but you're not sure it's feasible. A reference book on solar energy shows that the ground-level solar intensity in your city is 800W/m2 for at least 5 hours a day throughout most of the year. Assuming that a completely black collector plate loses energy only by radiation, and that the air temperature is 20掳C, what is the equilibrium temperature of a collector plate directly facing the sun? Note that while a plate has two sides, only the side facing the sun will radiate because the opposite side will be well insulated.

A 2000 cm3 container holds 0.10 mol of helium gas at 300掳C. How much work must be done to compress the gas to 1000 cm3 at (a) constant pressure and (b) constant temperature?
