Apply scientific reasoning solid
substance a has a melting point of 100°c.
liquid substance b has a freezing point of
110°c. for each substance, identify its state
of matter, and describe the motion of its
particles, when the substance is at 115°c.

The answer is below both substances are liquids.

Explanation:

Substance A

This substance has a melting point of 100°C, this menas that at 115°C, is a liquid. In this state of matter, particles can move, they are not fixed, and can take the shape of a container.

Substance B.

This substance has a freezing point of 110°C, at 115°C, is also a liquid, then the particles can move because they are not fixed, and can take the shape of its containe.
