What happens in a chemical change that does not occur in a physical change?
Andrej [43]

Answer:

In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition. Although we call them physical "reactions," no reaction is actually occurring.

When an object is lifted 6 meters off the ground, it gains a certain amount of potential energy. If the same object is lifted 18
AlexFokin [52]

Answer:

The answer to your question is the letter C. three times as much

Explanation:

Data

First step = 6 m

Second step = 18 m

Potential energy is the energy stored that depends on its position.

Formula

Pe = mgh

m = mass; g = gravity; h = height

Potential energy of the first step

        Pe1 = 6mg

Potential energy of the second step

        Pe2 = 18mg

-Divide the Pe2 by the Pe1

        Pe2/Pe1 = 18mg/6mg

                       = 3
