You can tell if the sugar is still there by boiling off the water and leaving the sugar behind in the container. Sugar is a solid, and therefore cannot evaporate, so when the water reaches boiling point, it will evaporate at a quicker rate than before (water evaporates at any temperature in liquid form; just not enough to be noticeable) and leave the container to become water vapour
Answer:
<h2>2540.16 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 72 × 9.8 × 3.6 = 2540.16
We have the final answer as
<h3>2540.16 J</h3>
Hope this helps you
That is potential energy.
Answer:
air humidity
Explanation:
Air parcel is a blob of air which moves in the atmosphere. For stability, if the air parcel is displaced vertically then it returns to the original position.
The most important points to know of the rising air parcel are the air humidity of the air, the temperature of the air and its dew point. These are the critical information to determine the stability of the air.
The air parcel rises buoyantly as it gets warmer than the surrounding environment.
