THERMODYNAMICS EXAM 1 (CH.1-3) DEFS. | QUESTIONS
AND ANSWERS | 2026 UPDATE | WITH COMPLETE SOLUTION.
System Answer - whatever we want to study
Surroundings Answer - everything external to the system
Boundary Answer - system is distinguished from its surroundings
Closed System Answer - when a particular of matter is under study.
Control Volume Answer - A given region of space through which mass and
energy may flow. Mass may cross the boundary of a control volume.
Property Answer - is a macroscopic characteristic of a system to which a
numerical value can be assigned
State Answer - the condition of a system as described by its properties
Process Answer - is a transformation from one state to another
Extensive Property Answer - Depends on the size or extent of a system.
its value for overall system is the sum of its values for the parts into which
system is divided.
, Intensive Property Answer - Independent of size or extent of the system
Equilibrium Answer - a condition of balanced maintained by an equality of
opposing forces.
Specific Volume Answer - reciprocal of the density v=1/p volume per unit mass
Pressure Answer - Fnormal/Area
Temperature Answer - a physical property that determines when they will be
in thermal equilibrium.
Kelvin Scale Answer - absolute temperature scale whose unit of temperature is
the kelvin(K) an SI Base unit for temperature.
Rankine Scale Answer - -An absolute thermodynamic temperature scale with
absolute zero that coincides with the absolute zero of the kelvin scale
An English base unit for temperature
How to Solve Thermodynamic Problems Answer - 1. Known
2. Find
3. Schematic and Given Data
4. Engineering Model
5. Analysis
Isolated System Answer - a special type of closed system that does not interact
in any way with its surroundings
