Answer:
Option (a): Melting point and freezing point are will be the same when crystallization.
Explanation:
When crystals form from the mechanism of crystal growth, it’s known as crystallization. A crystal is a solid type of material which is having a regular pattern of atoms and molecules.
Temperature of a compound which changes its physical state from solid state to liquid state is known as melting point temperature.
Temperature of a compound which changes its physical state from liquid state to solid state is known as the freezing point temperature.
Most of the liquids are freeze by the method of crystallization. The temperature of the system remains nearly equal to melting point.
Further Explanation:
Basically there are two types of crystallization processes. They are the cooling and evaporation crystallization.
Salts, sugar and gemstones are some examples for crystals.
Crystallization consists with two steps; Nucleation and Crystal growth. In nucleation; solute molecules dispersed in the solvent are gather in to clusters. These clusters need to reach a critical size to become stable nuclei, by factors such as temperature and super saturation.
After nucleation, crystal growth happens. In this process the nuclei increases its size to a critical cluster size.
In crystal growth solute molecules precipitate out of solution. Then they dissolve back into solution.

O rotation of the Moon on its axis
O revolution of the Moon around Earth
O revolution of the planets around the Sun
Answer:
revolution of the planets around the Sun.
Explanation:
The revolution of the planets around the Sun is a result of the gravitational force exerted by the Sun. The Sun's gravitational pull attracts the planets, causing them to move in an elliptical orbit around it. This motion is known as the revolution of the planets around the Sun. The other options listed (rotation of the planets on their axes, rotation of the Moon on its axis, and revolution of the Moon around Earth) are also related to motion and gravity, but they are different phenomena.
Answer:
To find time to reach maximum height given initial velocity use the equation Vf=vi+at. At the maximum height, the object has no initial velocity left and therefore you can substitute 0 for the Vf in the equation.

Rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
The largest displacement of sound wave constituents from their resting positions is referred to as amplitude. It stands for the loudness or intensity of a sound, to put it simply. Here are some illustrations of both high and low-amplitude sounds:
High Amplitude Sound: An illustration of a high amplitude sound is a rock concert with loudspeakers blaring songs at full intensity. The concert speakers produce sound waves with a tremendous amplitude, creating a powerful, strong sound that can be heard from a great distance.
Low Amplitude Sound: A low amplitude sound is something like the sound of a whisper. The sound created when someone whispers is calm and soft and not as loud as a rock concert, since the sound waves produced have a tiny amplitude.
In both cases, how loud or soft the sound is perceived by our ears depends on the amplitude of the sound waves. Low-amplitude sounds are soft and quiet, but high-amplitude sounds are strong and loud.
Hence, rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
