The diagram below represents the setups a teacher showed students for an investigation about a closed system. In Setup 1, the teacher placed a balloon over the top of a container that has some water in it. The total mass of this closed system was 460 grams. In Setup 2, the teacher used appropriate safety equipment and followed all safety procedures as the container was placed on a stand above a heat source for five minutes. Why did the balloon inflate?

• The teacher added a tube for the balloon

• The teacher added a heat source and turned the water into a gas

• The teacher raised the container so it was higher

• The teacher added more water for the balloon

A teacher did a demo lesson for her students with a balloon. Setup 1 and Setup 2 are a CLOSED system. Using the picture, complete the bar graph to represent the masses (in grams) of this closed system in Setup 1 and Setup 2 by coloring in how much each one weighs (mass). The bar graph does not have to look perfect.
