Question

the specific temperature at which a substance changes from a liquid to a gas is an example of a a. chemical bond. b. chemical change. c. physical property. d. chemical property.

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

A specific temperature at which a substance is changing from solid state to liquid state is known as boiling point.

When there occurs no change in chemical composition of a substance then it is known as a physical property.

For example, when ice melts it changes into liquid.

Whereas when there occurs change in chemical composition of a substance then it is known as a chemical property.

For example, formation of methane gas from carbon and hydrogen atom is a chemical change.

Thus, we can conclude that the specific temperature at which a substance changes from a liquid to a gas is an example of a physical property.

Answer 2

Physical property because going from a liquid to a gas doesn't change it's chemical composition only it's physical state
