Thermodynamics: 1st Law for Closed Systems (8 of 25)

0:00:13 - Reminders of how to find properties and first law for closed systems
0:02:38 - Example: First law for closed system, rigid tank
0:33:13 - Example: First law for closed system, rigid tank
1:02:37 - Example: First law for closed system, piston-cylinder (continued next lecture)

This lecture series was recorded live at Cal Poly Pomona during Winter 2017. The textbook is Cengel and Boles, "Thermodynamics: An Engineering Approach (8th edition)."

whoever came with the idea of putting all of this up on Youtube . Thank YOU hopefully u stay well during this coronavirus outbreak and ur family

Thank you for these videos! I really enjoy the flow of your teaching. It's very easy to follow.

[sunnykalra]

these lessons are amazing thank you so much. you have explained this so well

Great material and instruction. Only thing that may help further the constant volume process, conceptually that helps deliver the whole picture: constant volume is a vertical line on the Tv diagram, and the area under the curve is the work done by the process. There is no area under a line, therefore 0 work is done.

How do you know that point 1 is on the right of the vertical hump line of the Tv curve? What would happen if point 1 were on the left side of the hump, and you can only move up towards a saturated liquid or compressed liquid? Seems weird you would be adding heat to the system but it would only get more compressed

how can we say in 2nd question that volume is same, Work done by boundery = 0 . but I think volume changes as liquid converts to vapour ???

Why session 20 is just 24 seconds?
would you please upload the complete session?
