B. remains the same
C. increases

D. decreases
A law which states that “A particle
remains at rest or continues to move
with uniform velocity if there is no
unbalanced force acting on it” is known
as:
A. Newton’s second law of motion
B. Newton’s law of gravitation
C. Newton’s first law of motion
D. Newton’s third law of motion

The area of thermodynamics concerned
with the measuring of thermal
properties is called what?
A. psychrometrics
B. chemometrics
C. thermoeconomics
D. calorimetry
D. calorimetry
One technique we can use to measure
the amount of heat involved in a
chemical or physical process is known
as calorimetry. Calorimetry is used to
measure amounts of heat transferred to
or from a substance.
The Diesel Cycle consists of what
processes?
A. 2 isentropic, 2 isobaric
B. 1 isentropic, 1 isobaric, 2 isometric
C. 2 isentropic, 1 isobaric, 1 isometric
D. 1 isentropic, 2 isobaric, 1 isometric
C. 2 isentropic, 1 isobaric, 1 isometric
In second law of thermodynamic, which
of the following state that no heat
engine can have a thermal efficiency of
100% or as far as power plant to
operate, the working fluid must
exchange heat with the environment as
well as the furnace.
A. Clausius Statement
B. Clausius-Planck Statement
C. Kelvin Statement
D. Kelvin-Planck Statement
D. Kelvin-Planck Statement
The Kelvin-Planck statement is: “it is
impossible for any device that operates in a cycle to receive heat from a single reservoir and produce a net amount of work.” Another common statement is the
Clausius statement: “It is impossible to construct a device that operates in a cycle and produces no effect other than the transfer of heat from a lower-temperature body to a higher-temperature body.”
Doubling the distance between the
center of an orbiting satellite and the
center of the earth will result in what
change in the gravitational attraction of
the earth for the satellite?
A. one-half as much
B. four times as much
C. one-fourth as much
D. twice as much
C. one-fourth as much
A block of aluminum and a block of iron each absorb the same amount of heat,and both blocks remain solid. The mass of the aluminum block is twice the mass of the iron block. If the specific heat of aluminum is twice the specific heat of iron, then:
A. the increase in temperature of the
aluminum block is the same as increase in
temperature of the iron block
B. the increase in temperature of the
aluminum block is four times the increase
in temperature of the iron block
C. the increase in temperature of the iron
block is four times the increase in
temperature of the aluminum block
D. the increase in temperature of the iron
block is twice the increase in temperature
of the aluminum block
C. the increase in temperature of the iron
block is four times the increase in
temperature of the aluminum block
A load that is exerted on a surface or
body that does not change in magnitude
or position with time:
A. Sustained load
B. Concentrated load
C. Impact load
D. Static load
D. Static load
Impact load means the load applied by
a moving object (Like a blow). The
application time of this load is negligible, as opposed to other loads which are applied gradually or over a long period of time.
Static load are force exerted on a
surface or body that does not change in
magnitude or position with time.
Concentrated load is a load acting on a
very small area of the structure’s
surface; the exact opposite of a distributed load.
Sustained loads are the loads which act
throughout the service life of the
structure. These loads include the self-
weight of the structure and
superimposed dead loads on the
structure such as parapets, crash
barriers, surfacing and fills over the
structure.
