Bottle is a Closed System Interactions: Sub- System

2. Citric Acid + Baking Soda chemically react Bottle 4. Carbon Dioxide gas formed 3. Water and Sodium Citrate are formed 1. Tablet dissolves into Sodium and BiCarbonate Ions in H2O Heat Energy into Breaking up (dissolving Alka Seltzer ) Interactions are ingredients dissolving which takes Energy and then chemically reacting which releases Energy. In the closed bottle gas Pressure increases. Heat Energy released to form salt and water Dissolving Tablet Reacting Acid and Base Sound Energy

Open Beaker/Open System Interactions: Sub- System

2. Citric Acid + Baking Soda chemically react Water Open Beaker Carbon Dioxide gas molecules 3. Water and Sodium Citrate formed 1. Tablet dissolves into Sodium and BiCarbonate Ions Heat Energy into Breaking up (dissolving Alka Seltzer ) Heat Energy released to form salt and water 4. Carbon Dioxide Gas formed Interactions are ingredients dissolving which takes Energy and then chemically reacting which releases Energy. In the open beaker, carbon dioxide gas escapes into the room.
