By comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
<h3>What is melting point?</h3>
The melting point is the point at which the solid would change to liquid. The boiling point is the point at which a liquid would change to gas. Now we know that the melting and the boiling point of a signature of a compound and can be used to identify a pure substance.
Hence, by comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.

Gravitational attraction / field strength increases when closer; A light dependent resistor (LDR) can be used as a sensor to detect light intensity.
Ball thrown into the air at an angle.
Answer: The correct answer is "perpendicular".
Explanation:
In a transverse wave, the particles of the medium vibrates perpendicular to the direction of the motion of the wave.
For example, light wave.
It does not need medium to propagate. It can travel in vacuum. It travels with the speed of the light.
In a longitudinal wave, the particles of the medium vibrates parallel to the direction of the motion of the wave.
For example, sound wave.
Therefore, In a transverse wave, the motion of the disturbance is perpendicular to the wave motion.
