The answers are as follows:

1. / - The change is from solid to gas. The solid air freshener dissolves into the air and changes into a gas.

2. x - Acetone is present in the liquid form which mixes into the air and changes into a gas.

3. / - Dry ice is a solid which dissolves into air. Hence it changes from solid to liquid.

4. / - The solid air freshener goes through the process of sublimation and changes into a vapor.

5. x - The wetness of the hair is water which is a liquid. The water gets evaporated into the air. Hence it is a liquid-to-gas change.
