If you stop talking, it is quiet., If you heat water, it boils., If you turn the key, the car starts., If you mix red and blue, you get purple., If children study hard, their parents are happy., If you freeze water, it becomes ice., If you press this button, the computer turns on., If you heat metal, it expands., The baby wakes up if we make too much noise,, I get tired if I work too much.,
