Answer:
About 2 units.
Explanation:
We assume that there is no heat dissipating instrument in the room
Total cooling load of the room is defined from the given below equation
=
+
+
where
= 10*100 W =1 KW
= 40*360 KJ/h= 4 KW
=15000KJ/h= 4.17 KW
= 1+4+4.17=9.17 KW
the number of air conditioner unit is =
=1.83
which is approximately 2 units
Answer:
The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days
Hey!
The upper, plastic-like part of earth that the plates ride on are called the (Asthenosphere)
I hope this helps! :)
Since the system itself is giving off heat, this is a
reduction in the internal energy.
heat = - 25,000 J
Since work is being done on the system, therefore it is
an additional energy to the system. Work is given as:
work = - P dV
work = - 1.50 atm (6 L – 12 L)
work = 9 L atm
Since it is given that 1 L atm is equivalent to 101.3 J,
therefore the total energy added is:
energy due to work = 9 L atm (101.3 J / 1 L atm)
energy due to work = 911.7 J
Therefore the total change in internal energy is the sum
of heat and energy due to work:
Change in internal energy = - 25,000 J + 911.7 J
Change in internal energy = - 24,088.3 J
<span>Therefore, approximately 24.1 kJ of energy is lost by the
system in the total process.</span>
