TAILIEUCHUNG - Lecture Thermodynamics

In mechanics we deal with quantities such as mass, position, velocity, acceleration, energy, momentum, etc. Question: What happens to the energy of a ball when we drop it on the floor? Answer: It goes into heat energy. Question: What is heat energy? | Thermodynamics Temperature, Heat, Work Heat Engines Introduction In mechanics we deal with quantities such as mass, position, velocity, acceleration, energy, momentum, etc. Question: What happens to the energy of a ball when we drop it on the floor? Answer: It goes into heat energy. Question: What is heat energy? The answer is a bit longer. In Thermodynamics we deal with quantities which describe our system, usually (but not always) a gas. Volume, Temperature, Pressure, Heat Energy, Work. We all know about Volume. Pressure: Demonstrations: Balloons, Bed of Nails, Magdeburg hemispheres. Example 120 lb woman putting all her weight on 2in2 of heals. Pressure = 120 lb/2in2 = 60 lb/in2. Is that a lot? Comparison: 1 atm = lb/in2. Thus of heals is approximately 4 atm. This is the pressure you would feel at a depth of approximately 133 ft of water. Temperature and Heat Everyone has a qualitative understanding of temperature, but it is not very exact. Question: Why can you put your hand .
