Physical Chemistry Flashcards
A branch of chemistry that deals with the study of the structures and physical properties of matter with the laws of chemical interaction and the theories governing these interaction
Physical chemistry
Involve the kinetic theory of gases and its application to solution and Debye-Heckel theory of electrolytes
Newtonian Mechanics and Electrostatics
Involved motion of individual molecules and individual electronic, spin, vibrational, and rotational energy transitions
Microscopic
Involves measurement of properties of matter as a bulk such as pressure, temperature, volume and absorbance
Macroscopic
It results from a mic true of neutral atoms, free electrons and charged ions usually s fluid but due to charged particles present, it responds to and generates electromagnetic forces
Plasma
Special state of matter in which atoms in a confined gas act together like a single giant particle after being cooked cryogenically to a temperature near absolute zero
Bose-Einstein Condensate
Refers to the physical state of gas specified in terms of its physical properties like volume, pressure, temperature and number of moles
State of a system
In the kinetic molecular theory, gases are considered to be composed of minute discrete particles called
Molecules
The molecules within a container are believed to be ceaseless chaotic motion during which they collide with each other and with the walls of the container
Kinetic molecular theory
Inasmuch as the pressure of a gas within a container does not vary with time at any given temperature and pressure, the molecular collision must involved no energy loss due to fiction.
Kinetic molecular theory
In the kinetic molecular theory, all molecular collisions are considered to be perfectly
Elastic
The absolute temperature is s quantity proportional to the average kinetic energy of all molecules in a system
Kinetic molecular theory
At relatively low pressures, the average distances between molecules are large compared with molecular diameters and hence the attractive forces between molecules may be considered negligible
Kinetic molecular theory
The vapor density method of the determination of molecular weight is developed by
Jean Baptiste Andre Dumas
The regnant method of the determination of molecular weight is developed by
Henry victor Renault
As soon as equilibrium is established between the liquid and vapor,mother pressure exerted by the vapor is known as the
Saturated vapor pressure
When the critical point is reached, there is or no distinction between the liquid and the vapor
No
The resistance offered by the fluid to the flow of another fluid
Viscosity
It is produced by the shearing effect of moving one layer of the fluid past another
Viscosity
Viscosity increases with increasing temperature when it come to
Gases
The pouiseuille equation is also known as
Ostwald viscosimeter
This law if applicable with the radius of the falling body is greater than the distance between the molecules of the liquid
Stokes law
The du Nouy Ring Method uses a device called
Tension enter
The tensiometer was developed in
Rockefeller institute for medical research
