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.
The answer is: Motion!

Answer:
The second law of thermodynamics describes the direction in which heat is transferred between systems, <u>heat is a form of energy</u> in transition.
This law says that heat or energy always flows spontaneously from the body or system with a higher temperature to a lower temperature system (from something hot to something cold, and not the other way around).
This is why if we leave an ice at room temperature it will eventually melt, because <u>the environment transferred energy to the ice</u> and caused its temperature to increase and thus to turn into a liquid form.
The second law can also be interpreted in terms of entropy, and tells us that entropy, which is often interpreted as a measure of disorder, always increases.
