True or false: and a physical change some of the physical properties of the substance may be altered in the chemical composition remains the same?

True, in a physical change, some of the physical properties of the substance may be altered but the chemical composition remains the same.

Option True

Explanation:

The matter can undergo variations in physical or chemical. The physical changes of a matter occur when the matter undergoes changes in the physical properties like change in the state of matter, weight, etc.

But the matter's chemical compositions will remain constant in case of matter undergoing physical change. While in chemical change, the matter will undergo change in the composition but there will be no change in the physical properties. Hence, the given statement is true about a physical change.

we need to know the time interval during which the force acts. impulse of force = momentum change
