No, interatomic bonds aren't broken during boiling.
Yes, intermolecular forces are overcome when water boils.
<h3><u>Explanation:</u></h3>
Boiling of water is a physical change of state that converts the liquid water into water vapour. This process takes place in 100°C.
In liquid water, there are different forces of attraction between the molecules of water, most importantly the van der Waal's force, and the hydrogen bonds. van der Waal's forces are very weak, so of negligible importance. But hydrogen bonding are of significant strength. They are present between the hydrogen atoms and the oxygen atoms of different molecules of water. During boiling, these forces are weakened by the increasing kinetic energy of molecules and the water molecules start to boil off as water vapour. There's no breaking of interatomic bonds, which would have produced hydrogen and oxygen gases instead of water vapour.

Answer:
The fish is experiencing a water pressure of 502.8 kPa.
Explanation:
The water pressure the fish is experiencing can be found as follows:
(1)
Where:
g: is the gravity = 9.81 m/s²
h: is the height (depth) = 50.0 m
ρ: is the seawater's density = 1.025 g/cm³
By replacing the above values into equation (1) we have:
Therefore, the fish is experiencing a water pressure of 502.8 kPa.
I hope it helps you!
The correct answer is the following.
The forces that act on the piano are: 2) gravitational force acting on the piano (piano's weight). 5) force of the floor on the piano (normal force). 7) force of Chadwick on the piano.
As we see in the picture that I have attached is Chadwick pushing the piano in a horizontal plane. So Chadwick is applying a force that produces an acceleration. It is his force on the piano plus the acceleration of the weight of the piano, it's a gravitational force. This is pure physics applied to an object.
