Answer: ALL CAREFULLY ANSWERED CORRECTLY.
Explanation:
1) A loaf of Bread PHYSICAL SYSTEM
✓ How can the environment affect the edibility of the bread
✓ What are the constituents that makes up the bread
✓ What process is involved in these constituents mixing to form the loaf.
2) The law of thermodynamics makes us to understand that when heat/energy passes through a system, the systems internal energy changes with respect to the conservation of energy law. That is energy lost = energy gained. Typically, ice would melt in a cup of hot tea because of the thermal energy in the molecules of the hot tea. When you heat a material, you are adding thermal kinetic energy to its molecules and usually raising its temperature. The temperature of the ice raises due to the kinetic energy added to it and it melts to water.
3) The theory of systems view the world as a complex system of interconnected parts. If we consider the society; (financial systems, political systems, etc) we will agree that they individually have their own components and it's the summation of this components that makes the system, this implies that system thinking could be applicable in this kinda of systems as long as they are made up of components.
4) Technology has boosted every sector of our lives and it has the capacity to do more. Restricting it's importance to entertainment alone would be an underusing of its potentials. Engineering students infact should not need any drive to be encouraged about maximizing all it can do in shaping our world.
5) ~ Nature shows its splendid soul
~Never ceases to leave us in amazement
~And we are in love
Answer: Borderline personality Disorder.
Explanation: This is a type of mental disorder which could affects mood, behavior and relationships.
Its symptoms includes unstable emotions, sense of insecurity, worthlessness, and impulsivity.
This condition can not be cured, but treatments such as therapies, medication (in some cases) could help.
Answer:
ummm why is you doing this
Explanation:
It doesnt make sense.
Answer:
a) 1 m^3/Kg
b) 504 kJ
c) 514 kJ
Explanation:
<u>Given </u>
-The mass of C_o2 = 1 kg
-The volume of the tank V_tank = 1 m^3
-The added energy E = 14 W
-The time of adding energy t = 10 s
-The increase in specific internal energy Δu = +10 kJ/kg
-The change in kinetic energy ΔKE = 0 and The change in potential energy
ΔPE =0
<u>Required </u>
(a)Specific volume at the final state v_2
(b)The energy transferred by the work W in kJ.
(c)The energy transferred by the heat transfer W in kJ and the direction of
the heat transfer.
Assumption
-Quasi-equilibrium process.
<u>Solution</u>
(a) The volume and the mass doesn't change then, the specific volume is constant.
v= V_tank/m ---> 1/1= 1 m^3/Kg
(b) The added work is defined by.
W =E * t ---> 14 x 10 x 3600 x 10^-3 = 504 kJ
(c) From the first law of thermodynamics.
Q - W = m * Δu
Q = (m * Δu) + W--> (1 x 10) + 504 = 514 kJ
The heat have (+) sign the n it is added to the system.
