Explanation:
The water molecules begins to leave their fixed position and begins to move as the temperature increases.
When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.
- The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
- In the ice, the molecules are locked and fixed in the lattice
- As the temperature increases, the average kinetic energy of the particles rises.
- This makes the structure of the ice to collapse and forms liquids.
- By the virtue of this, they flow and move over one another
- With increasing temperature, the bonds are broken and vapor forms
Answer:
He could have many different hypothesis, but here is one.
Explanation:
If rubber bands are wider, then the rubber bands will stretch further, because the wider a rubber band is the stronger it is.

(d)
Initial energy of the system, which is the same as the initial energy in the 
capacitor:
.
Change in energy:

D
Because if an object is moving at a constant speed the force of friction must equal the applied (horizontal) force, and for it to be accelerating or decelerating, the force of friction and the applied force must be unequal
