Answer:
At 100°C, the pH of pure water is 6.14. That is the neutral point on the pH scale at this higher temperature. A solution with a pH of 7 at this temperature is slightly alkaline because its pH is a bit higher than the neutral value of 6.14.

Because of Surface tension
Answer:
It would break because how fast and how tall the fall is because at a certain hight water can act like a solid and break your body/bones or you could die
its a do or die situation
Explanation:
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, 
kg
Height to which the object is raised above his head, 
m
Acceleration due to gravity is, 
m/s²
We know that for a mass 
raised to a height 
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
