E. Acceleration is the answer
Answer:
phenomenon is dry adiabatic lapse rate
Explanation:
air babble elevation = 1000 meters
temperature = 10 degree decrease
to find out
phenomenon is best described as
solution
we know bubble is unsaturated air is rising through the atmosphere
bubble reach height 1000 meter and temperature 10 degree
than phenomenon is dry adiabatic lapse rate
because when parcel of air is lift and pressure decrease with height and temperature fall down by expansion and rate of temperature fall 1°C /100 m in dry Adiabatic lapse rate parcel descends to higher pressure and temperature then increase at rate 1°C / 100 meters
this his phenomenon is dry adiabatic lapse rate
Answer:
a) Qh= 6750 kJ
b) e = 0.296
c) = 390.625° C
Explanation:
Given:
Work done, W = 2000 kJ
Heat flow, Q = 4750 kJ
Temperature at which heat flows out, = 275° C
a) Now, the heat flow through the engine (Qh)
Qh = W + Q
or
Qh = 2000 + 4750
or
Qh= 6750 kJ
b) The efficiency (e) is given as:
on substituting the values, we get
or
e = 0.296
c)
where,
is the temperature at which heat flow
on substituting the values, we get
or
= 390.625° C
Definition of Entropy:
The measure of a systems thermal energy per unit temperature
that is unavailable for doing useful work.
