MAE 201 Exam 1 Questions With Correct
Answers
thermodynamics - CORRECT ANSWER✔✔-the science that deals with | | | | | | | |
heat and other forms of energy (work), their transformations, and their
| | | | | | | | | | |
relationships with properties of substances | | | |
engineering goal - CORRECT ANSWER✔✔-to make energy conversion as
| | | | | | | | |
efficient as possible under the constraints of cost, space, and safety
| | | | | | | | | |
system - CORRECT ANSWER✔✔-a collection of matter in a 3D region of
| | | | | | | | | | | |
space bounded by an arbitrary surface
| | | | |
closed system - CORRECT ANSWER✔✔-A system in which no matter is
| | | | | | | | | | |
allowed to enter or leave but energy is
| | | | | | |
closed system w/ rigid boundary - CORRECT ANSWER✔✔-same as a
| | | | | | | | | |
closed system but with constant volume (dV=0)
| | | | | |
closed system w/ moving boundary - CORRECT ANSWER✔✔-volume of
| | | | | | | | |
the system is not constant but mass can still not pass (ex. piston-cylinder
| | | | | | | | | | | |
device)
|
, open system - CORRECT ANSWER✔✔-A system in which matter can
| | | | | | | | | |
enter from or escape to the surroundings.
| | | | | |
boundary - CORRECT ANSWER✔✔-a zero volume surface, usually
| | | | | | | |
located at the interface between two materials (b/w the system and its
| | | | | | | | | | | |
surroundings)
isolated system - CORRECT ANSWER✔✔-a system not influenced by its
| | | | | | | | | |
surroundings. No heat or energy crosses boundary | | | | | |
property - CORRECT ANSWER✔✔-any measurable characteristic of a
| | | | | | | |
system that do not depend on how the system arrived at its current
| | | | | | | | | | | | |
condition
extensive property - CORRECT ANSWER✔✔-depends on the size of the
| | | | | | | | | |
sample
1. volume
|
2. mass
|
3. total energy/enthalpy/entropy
| |
4. all mass dependent properties
| | | |
5. 1st and 2nd laws of thermo
| | | | | |
