A student observes dew on her lawn early in the morning. After the sun hits the surface of the lawn, the dew disappears. Is this evidence for a physical or a chemical change in the H2O molecules of dew?

    Do you know the definition of physical and chemical change?

    A physical change is any change that is NOT involving a change in the substance's chemical identity.

    And Chemical change is any change that results in the formation of new chemical substances.

    So out of the two which do you think would have to do with the dew disappearing? @iwanttostudy236

    @iwanttostudy236 What exactly happened to the dew? What was it converted into?
