The First Law of Thermodynamics - Proses dalam mesin anda

•Today’s lecture topics:

–The First Law of Thermodynamics

•Forms of energy

•Types of processes

 *. Energy have many different form: 

     - Kinetic

     - Internal

     - Potential

     - Mechanical

     - Chemical

     - Electrical

  

Energy is Conserved

Ø  E = constant

                       (EKinetic + EPotential + EInternal + EChemical + EMechanical + EElectrical ) = constant

Work is a Form of Mechanical Energy

Work = Force x Distance

dW = F Dx

cape mnjelaskan,hehe,,to the point aj deh...

*. Hukum termodinamika yg berlaku dengan mesin yaitu di dlm ruang bakar sebagai berikut:

*. hubungan antara temperature, pressure, volume, mass. Types of Processes

 

–        Isochoric (or Isosteric)

–        Isobaric

–        Isothermal

–        Adiabatic (later lecture)

 *. Isochoric Process

             Changes in

–        Heat Added or Removed

–        Temperature

–        Pressure

 

 *. Isobaric Process

•          Changes in

–        Heat Added or Removed

–        Temperature

–        Volume

 

*. Isothermal Process

•          Changes in

–        Heat Added or Removed

–        Pressure

–        Volume
