Chapter 8 - Thermal

Note - Mastering Physics asks for 2 significant figures, but for multi-step questions they will use the unrounded or 3 sig fig values from earlier parts. 

​The textbook and Mastering Physics occasionally uses 1.1 atm instead of 1.0 atm. Be careful with your calculations. 

Read the following chapters in the textbook:
  • Chapter 9
  • Chapter 12
  • Chapter 13
​
  • Thermal #1
         Page 458 - Problem 44
         Online - Heat Flow through a Sectional Rod


Hint - #44 need to use the average radius when you take into account the thickness of the igloo

Hint - #44 the equation for Area of a Hemisphere can be found online, google it


  • Thermal #2
         Page 352 - Multiple Choice 7, 9
         Page 354 - Problems 27, 32
         Page 357 - Reading 78, 79, 80
         Page 454 - Multiple Choice 1, Concept 22

Hint - #32 watch your units! Convert atm to Pa for pressure. Convert the answer from molecules/m3 to molecules/cm3 before submitting to Mastering Physics
        
  • Thermal #3
         Page 351 - Multiple Choice 3, 4, 6
         Page 353 - Concept 23
         Page 353 - Problems 7, 23, 25
                 
  • Thermal #4
         Page 455 - Multiple Choice 4
         Page 456 - Problems 3, 5, 6
         Online - Understanding PV diagrams and Calculate W

Hint - #3d for pressure they use 1.1 atm, also for the mass you know that it is Helium - what's the atomic # of He and how is that helpful?

Hint - Online Tutorial - be very careful with work ON and work BY, they are opposites of each other

         
  • Thermal #5
         Page 352 - Multiple Choice 10, 11
         Page 355 - Problem 53
         Online - Isobaric Expansion PV plots
         Online - Work in PV plane

Hint - Online Tutorials - be very careful with work ON and work BY, they are opposites of each other
          
  • Thermal #6
         Page 354 - Problem 40
         Page 457 - Problem 24
                     
  • Thermal #7
         Page 355 - Problems 70
         Page 457 - Problems 21, 26
         Online - Expansion and Compression of Gas
       
  • Thermal #8
         Page 489 - Problem 26 (SKIP part H!)
         Online - Various Gas Expansion

Hint - #26h - enter 0.18 for part h (efficiency is no longer part of the curriculum)
