Fundamental Chemistry Flashcards
Terms used when heat is generated by the combustion process is transferred from the system of chemical reaction to surroundings.
Exothermic Process
This is the study of the interconversion of heat and other kinds of energy.
Thermodynamics
If two systems are in both thermal equilibrium with a third system, then they are in thermal equilibrium with each other. What is this law of thermodynamics?
Zeroth Law
The total energy of isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed. What is this law of thermodynamics?
First Law of Thermodynamics
It implies existence of a quantity called the entropy of a thermodynamic system. What is this law of thermodynamics?
Second Law of Thermodynamics
A system’s entropy approaches a constant value as its temperature approaches to absolute zero. What is this law of thermodynamics?
Third Law of Thermodynamics
In second law of thermodynamics, the __________ of the universe increases in a spontaneous process and remains unchanged in an equilibrium process.
Entropy
What happens to the entropy in an isolated system?
Never decreases
This is the method of heat transfer when touching heated pan?
Conduction
Identify what kind of heat transfer , when heat is transferred without any medium.
Radiation
How many hydrogens and lone pairs of electrons occupy the corners of a water molecule?
2 Hydrogens, 2 lone pairs of electrons
H-H
TRUE or FALSE?
Chiral Carbon is also known as a symmetric carbon?
False, Chiral carbon is also known as ASYMMETRIC carbon
This general principle helps predicts the direction in which an equilibrium will move when there is a change in concentration, pressure, volume and temperature.
Le Chantelier’s Principle
Thermodynamic process occurring at constant volume
Isochoric Process
Thermodynamic process occurring without loss or gain of energy by heat.
Adiabatic Process
