<h3>What is a freebody diagram?</h3>
The term Freebody diagram refer to the diagram that could be drawn to show the forces that act on an object. We must note that the forces that act on a body determine the direction in which the body moves.
This is because, force is a vector quantity. As such the magnitude and direction of a force are both responsible when we are trying to determine the force that acts on the object.
Attached is the image of the upward motion of a vector that shows the forces that act on the vector. This is what we refer to as a Freebody diagram.

Evaporation is the process of turning from liquid into vapor.
Answer:
hope this helps!
Explanation:
Volume of the air bubble, V1=1.0cm3=1.0×10−6m3
Bubble rises to height, d=40m
Temperature at a depth of 40 m, T1=12oC=285K
Temperature at the surface of the lake, T2=35oC=308K
The pressure on the surface of the lake: P2=1atm=1×1.103×105Pa
The pressure at the depth of 40 m: P1=1atm+dρg
Where,
ρ is the density of water =103kg/m3
g is the acceleration due to gravity =9.8m/s2
∴P1=1.103×105+40×103×9.8=493300Pa
We have T1P1V1=T2P2V2
Where, V2 is the volume of the air bubble when it reaches the surface.
V2=
Answer: Option (C) is the correct answer.
Explanation:
When we heat a fluid then the movement within the fluid makes hot (less dense) material to rise and cooler (more denser) material to sink at the bottom. This process is known as convection.
Thus, in the diagram hot (less dense) water will rise and cooler (more dense) water sinks at the bottom.
Therefore, we can conclude that according to the arrow the label belongs to cooler water sinks.
