Thermodynamics Problems Chapter 1
Work, Power, and Machines. What is Work? transfer of energy to a body by application of a force that causes body to move in direction of force. W = F.
Chapter 6 Energy Thermodynamics. 6.1 Nature of Energy The ability to do work or produce heat. Conserved - can be converted from one form to another but.
Fuel cell
Mechanics (work, energy and power)
Objectives Relate (without calculation) power to work done and time taken, using appropriate examples Recall and use the equation P = E/t in simple systems.
1 The First Law of Thermodynamics Closed System. 2 So far… We’ve considered various forms of energy Q (heat) W (work) E (Energy) We haven’t tried to relate.
Energy and Work 25 October 2011 Objectives Understand the term Work Done and be able to use the equation. Know that work done against friction results.
AGUS HARYANTO Part II. The conservation of energy principle can be expressed as follows: The net change (increase or decrease) in the total energy of.
Objectives
Free Energy and Temperature Free energy decreases (becomes more negative) as temperature At low T, G m for solid phase is lower than that of liquid or.
