Rita has two small containers, one holding a liquid and one holding a gas. Rita transfers the substances to two larger containers. Compare the behavior of the atoms in the liquid and in the gas once they are moved to the larger containers.
Liquids and gases are similar because they both take the shape of the container they are in. However, they are different because liquids have a definite volume, while gases do not and will expand to fill any available space. This is because the atoms in a gas move more freely than those in a liquid.
Explain how viscosity is related to the flow and attraction between atoms in a liquid.
Viscosity is a measure of a liquid's resistance to flow. When a liquid has high viscosity, it flows slowly because there is a strong attraction between its atoms or molecules, which prevents them from moving past each other easily. Conversely, liquids with low viscosity flow more quickly due to weaker intermolecular attractions.
Explain why the coin is able to float on top of the water in this glass.
The coin is able to float on top of the water due to surface tension. Water molecules at the surface are more attracted to each other than to the air above, creating a cohesive 'skin' or tension. If the coin is light enough and placed carefully, this surface tension is strong enough to support the weight of the coin and prevent it from breaking through the surface and sinking.
