Answer:
The slope of a position-time graph can be calculated as:

where
is the increment in the y-variable
is the increment in the x-variable
We can verify that the slope of this graph is actually equal to the velocity. In fact:
corresponds to the change in position, so it is the displacement, 
corresponds to the change in time
, so the time interval
Therefore the slope of the graph is equal to

which corresponds to the definition of velocity.

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.
