If a 6.0-kilogram box is moved from the floor to a storage compartment 2.0 meters above the floor, by how many joules does its gravitational potential energy change? round your answer to the tens place and include units with your answer.

The answer is 117.7 J.

Gravitational potential energy is the stored energy of the object as the result of its height:

E = m · g · h
where
E - the potential energy of the object:                  E = ?
m - the mass of the object:                                    m = 6 kg
g - gravitational acceleration:                                g = 9.81 m/s²
h - the height of the object:                                   h = 2 m

On the ground (h = 0), the gravitation potential energy does not exist: E = 0.
So, let's calculate it on the height of 2 m:
E = 6 kg * 9.81 m/s² * 2 m = 117.72 J ≈ 117.7 J

Sink to the bottom. addition of potassium nitrate past it’s dissolution capacity at a particular temperature will cause the extra to just sink to the bottom of the glass.however, if you were to raise the temperature of the solution prior to dissolving it, and then slowly decrease the temperature after the dissolution, you would create a “supersaturated” solution - a solution that has more solute dissolved into it than should be allowed. if you add any extra solute past this, the entire solution would “crystallize,” and this is how you get those cool videos on youtube.
