1. why did the volume of the gas molecules increased in the balloon after we hunclear text? draw and label what happened to tunclear text to increase in volume? draw and label what happened to tunclear text in this.

molecule
molecular motion. longer arrows = faster moving molecules

air in the balloon before it is warmed up by the heating pad

air in the balloon immediately after being warmed up by the heating pad

1. in which of the models (question 1) were the gas particles inside the balloon more densely packed together? how do you know? explain.

Explanation:

Step1: Analyze particle density

In the model of air in the balloon before it is warmed up by the heating - pad, the gas particles are more closely spaced.

Step2: Recall gas behavior with temperature change

When a gas is heated, its particles gain kinetic energy and move faster, spreading out. So the pre - heated state has denser packing.

Answer:

The gas particles inside the balloon were more densely packed together in the model of air in the balloon before it is warmed up by the heating pad. We know this because when a gas is heated, its particles move faster and spread out, resulting in less dense packing. In the pre - heated model, the particles are closer together.
