|
(A) |
The energy of the system is increased |
(p) |
System:
Process: |
A capacitor, initially uncharged It is connected to a battery
|
|
(B) |
Mechanical energy is provided to the system, which is converted into energy of random motion of its parts |
(q) |
System:
Process: |
A gas in an adiabatic container fitted with an adiabatic piston The gas is compressed by pushing the piston
|
|
(C) |
Internal energy of the system is converted in to its mechanical energy |
(r) |
System: Process: |
A gas in a rigid container The gas gets cooled due to colder atmosphere surrounding it
|
|
