What happens during evaporation? A gas changes to a liquid. 8. Butter going soft and runny on a hot day is an example of… solid turning to a liquid. 9. What is the missing word? When water is...., it starts to change from a liquid to a solid. When water is cooled, its starts to change from a liquid to solid. 10. Clouds are formed by hot air rising and falling rain. 11.
