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:
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
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
Page 353 - Concept 23 Page 353 - Problems 7, 23, 25
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
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
Page 457 - Problem 24
Page 457 - Problems 21, 26 Online - Expansion and Compression of Gas
Online - Various Gas Expansion Hint - #26h - enter 0.18 for part h (efficiency is no longer part of the curriculum) |
