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.

Radiation from the head is a major source of heat loss from the human body. Model a head as a 20-cm-diameter, 20-cm-tall cylinder with a flat top. If the body鈥檚 surface temperature is 35掳C, what is the net rate of heat loss on a chilly 5掳C day? All skin, regardless of color, is effectively black in the infrared where the radiation occurs, so use an emissivity of 0.95.

512 g of an unknown metal at a temperature of 15掳C is dropped into a 100 g aluminum container holding 325 g of water at 98掳C. A short time later, the container of water and metal stabilizes at a new temperature of 78掳C. Identify the metal.

2.0molof gas are at 30掳Cand a pressure of 1.5atm. How much work must be done on the gas to compress it to one-third of its initial volume at (a) constant temperature and (b) constant pressure? (c) Show both processes on a singlepVdiagram.

A gas cylinder holds 0.10 mol of O2 at 150掳C and a pressure

of 3.0 atm. The gas expands adiabatically until the volume is doubled.

What are the final (a) pressure and (b) temperature?

A container holds 1.0 g of oxygen at a pressure of 8.0 atm.

a. How much heat is required to increase the temperature by 100掳C at constant pressure?

b. How much will the temperature increase if this amount of heat energy is transferred to the gas at constant volume?
