Flashcards in Final Review Deck (16):
Pressure is the force/area, to increase pressure you:
A.) increase the area the force is applied to
B.) decrease the area the Force is applied
C.) increase the applied force
Both b and c
The zeroth law of thermodynamics states:
2 objects A/B are the same temperature and B/C are the same temperature, therefore A/C are the same temp and no heat will flow between them.
The first law of thermodynamics:
∆E= q + w
Second law of thermodynamics:
Energy flows from a hot object to a cool one
Third law of thermodynamics:
It is not possible to lower temperature of an object to absolute zero.
According to Pascal’s principal, if you ave a confined fluid at at given pressure, and an external pressure is applied:
The pressure is transmitted unchanged to every point within the fluid
Kinetic energy is different than potential energy in that kinetic energy is:
Energy in motion
(Potential energy is stored energy by virtue of position)
The amount of matter in an object
A bourdon gauge utilizes a coiled tube to measure:
The pressure difference between the pressure exerted by a gas in a cylinder and atmospheric pressure
Water has _________ surface tension.
Viscosity is the property which determines:
(Density determines turbulent flow)
T/F Pascal’s principle states that a confined fluid at a given pressure and the pressure is increased, it is transmitted unchanged to every point within the fluid.
Poiseuille’s Law explains:
The polycythemia patient has decreased blood flow through tissues and the anemic patient has increased flow through tissues.
Laminar flow is:
A.) smooth and orderly
B.) characterized by an unchanging flow pattern
C.) directly proportional to the 4th power of the radius
All of the above
T/F The law of La Place explains why the surface tension on a blood vessel wall depends on the radius of the vessel.
