Question

Identify one phase change you would see in a root beer float and describe what causes this change.

Answer 1

One phase change we would see in a root beer float is the change from liquid to gas.

Step-by-step explanation:

• In root beer float we can see all three states: solid, liquid and gas. Solid being the ice cream, beer as the liquid and the reaction after mixing the creates the gas.
• As we mix ice cream (solid) and beer (liquid) in a glass then the bubble formation process occurs which is called as carbonation creating the gas.
• Hence root beer float is a simple experiment showing all three states and change in phase from solid and liquid into gas.
