Concept explainers
Interpretation:
Whether the gas escape from the opened soft drink bottle is a physical or chemical change needs to be determined.
Concept introduction:
Physical changes, changes the forms of the chemical substance and doesn’t affect the chemical composition. The proportion of the chemical elements in the respective compounds remains same.

Answer to Problem 95A
It is a physical change.
Explanation of Solution
