Q9: Grace observed 50mL of a clear substance. She poured it from a cup into a bag and noticed that it flowed, and took the shape of the container, but the volume did not change. She then poured it into a container shaped like a box and noticed that again, it flowed and took the shape of the new container, but its volume remained the same. What state of matter was the substance that Grace was observing? solid liquid gas plasma Q10: Kylie mixed yeast, sugar, and water in a bowl and observed a bubbly foam begin to spill over the bowl. escribe the type of change that occurred and what evidence you have to support that claim.
