Question

Which statement best describes why a chemical change is different from a physical change? Responses A chemical change is used to identify characteristics of a substance, and a physical change identifies the behavior of a substance when in a reaction. A chemical change is used to identify characteristics of a substance, and a physical change identifies the behavior of a substance when in a reaction. A chemical change results in a different state of matter, and a physical change results in a new substance being formed. A chemical change results in a different state of matter, and a physical change results in a new substance being formed. A chemical change results in a new substance being formed; whereas, a physical change will result in a different state of matter. A chemical change results in a new substance being formed; whereas, a physical change will result in a different state of matter. A chemical change is used by scientists to create new substances, and a physical change happens naturally. A chemical change is used by scientists to create new substances, and a physical change happens naturally.

Answer 1

The distinction between a chemical change and a physical change is best illustrated by the sentence. A physical change will alter the state of matter, but a chemical change results in the formation of a new substance. Therefore, choice A is right.

How does chemistry change?

Chemical reactions between various substances have changed, leading to the creation of new chemicals. The chemical properties of the substance are unaffected by physical changes. Chemical compounds wouldn't alter as a result of the physical change. The matter's physical state may change as a result of the physical change.

A physical change causes the formation of a new substance, whereas a chemical change alters the state of matter.

A physical change occurs naturally, but a chemical change is exploited by scientists to make new compounds. A physical change will result in a different state of matter, but a chemical change produces a new substance.

So the phrase that contrasts a chemical change with a physical change is the most accurate. A physical change will alter the state of matter, but a chemical change results in the formation of a new substance.
