Answer:
Explanation:
In physics, work is defined as
Where is the word done, is the force that move the object and is the change of the position of the object.
In this case, we have
, remember that the difference refers to the actual subtraction between the final point and the initial point of the object.
Replacing these values, we have
Therefore, the right answer is C. The work done is 400 Joules
Answer:
400 J
Explanation:
I just took the test and can confirm this.
B)freezing
C)melting
D)boiling
At point B, the substance undergoes deposition, transitioning directly from a gas phase to a solid phase. The correct option is a.
At point B on the phase diagram, the phase transition occurring is deposition. Deposition is a physical process in which a substance transitions directly from a gas phase to a solid phase without passing through the liquid phase. This change is driven by a decrease in temperature or an increase in pressure.
During deposition, gas particles lose energy, causing them to slow down and come together to form a solid structure. This process is exemplified in nature when water vapor in the atmosphere turns directly into frost or ice crystals on a cold surface. Deposition is the opposite of sublimation, where a substance transitions from a solid to a gas without becoming a liquid.
