Answer:The change in entropy of the total amount of water is negative as a result of the mixing.
Explanation:If you increase temperature, you increase entropy
Also More energy gives you greater entropy and randomness of the atoms.
Answer:
b-energy is not exchanged
Explanation:
An isolated system is a thermodynamic system in which neither energy nor matter is exchanged with the surroundings.
As such the best statement that will fill the box under an isolated system is that energy is not exchanged.
- In an open system, both matter and energy are exchanged with the surrounding.
- A closed system is one in which energy transfer is permissible but matter is not exchanged.
- Energy cannot be created nor destroyed in any system. They are simply transformed.
Answer:
W = 320.30 J
Explanation:
To calculate the net work done over the block you take into account all implied forces:
(1)
The gravitational force and friction force are against the applied force F.
θ = 26°
F: applied force = 340N
Fg: gravitational force = Mg = (40.0kg)(9.8m/s^2) = 392N
Ff: friction force = 
Next, you replace to obtain the net force:
Finally, the net work, for 4 m, is:
Answer:
Refraction can occur only when light is transmitted
