CHM 110 Wk 1 – States of Matter: Basics Simulation

Visit the States of Matter: Basics Simulation, and follow these steps:

1. Click States from the Home screen.
2. From the Atoms & Molecules Menu on the top right, select Water.
3. Select the Solid Observe the atomic structure of water as a solid. Note the reading on the thermometer near the top of the container.
4. Select the Liquid Observe the atomic structure of water as a liquid. Note the reading on the thermometer near the top of the container.
5. Select the Gas Observe the atomic structure of the water as a gas. Note the reading on the thermometer near the top of the container.
6. Cool the container by clicking and holding the slider to “Cool,” under the container. Continue to cool the sample until the thermometer reaches the lowest possible reading. Observe the lowest reading and pay attention to the change in motion of the molecules as you do this.
7. Heat the container by clicking and holding the slider to “Heat.” Continue to heat the sample until the thermometer reaches the highest possible reading. Observe the highest reading and pay attention to the change in motion of the molecules as you do this.

Following completion of the simulation, write a 260- to 350-word response answering the following:

• What did you do during the simulation? Briefly describe.
• What did you observe?
• What do your observations teach you about the atomic nature of matter?
• What additional questions does this make you wonder about related to the atomic nature of matter?

In your response, include some of the new vocabulary introduced in this week’s reading, such as:

• Matter
• Atoms
• Molecules
• Solid
• Liquid
• Gas
• Mixture
• Mass
• Law of Conservation of Mass
• Temperature
• Heating
