, Problem 1.1 Conceptual Problem.
Definition of Thermodynamics:
Thermodynamics is the science that deals with the relationship of heat and mechanical
energy and conversion of one into the other.
ST
There are many everyday thermodynamics applications. Some examples are included in Chapter
1. Other examples include:
UV
Coaster brake on a bicycle converts mechanical energy of the moving wheel to frictional heating.
Refrigerator requires work input to transfers energy from the cold to the hot region.
The human body converts the energy from food to body heat and movement.
IA
Problem 1.2 Conceptual Problem.
_M
Device Form of Energy Input Form of Energy Output
Toaster Electrical energy Heat transfer from the hot
metal strips
Air conditioner Electrical energy Heat transfer from cold to hot
regions
ED
Light bulb Electrical energy Heating of bulb by electrical
resistance of the filament
Clothes iron Electrical energy Heat transfer
Refrigerator Electrical energy Heat transfer to kitchen
GE
Problem 1.3 Conceptual Problem.
E
A closed and open system can have:
K
a change of internal energy within the system
heat transfer in or out of the system at the system boundary
work transfer at the system boundary
??
a change in the volume of the system
Only an open system will have mass entering or leaving the system.
