Flour is a substance used to bake breads and cakes. Describe an experiment that would scientifically prove that flour should be classified as a solid and not as a liquid or not as a gas.
The theory that flour is a solid could be tested by determining if flour has a definite amount of space. Though flour conforms to the shape of a container, as a liquid does, this experiment will test to see what happens if the container is placed upside-down on a tray. When the container is removed slowly, the flour returns the shape of the container. A liquid would not.
