Gas

The video explains the behavior and properties of gas particles, highlighting their constant random motion and higher energy compared to liquids and solids. It discusses how gases fill containers, can flow, and be compressed. Additionally, it covers the theoretical possibility of any chemical existing as a gas under the right temperature conditions, provided it doesn't chemically break down.

What is a characteristic of gas particles in terms of their movement?

• They move randomly.

• They move in a circular path.

• They move in a fixed pattern.

• They are stationary.

How does the energy of gas particles compare to that of liquids and solids?

• Gas particles have no energy.

• Gas particles have less energy.

• Gas particles have the same energy.

• Gas particles have more energy.

What happens to gases in terms of filling a container?

• They fill only the bottom of the container.

• They fill the entire container.

• They fill only the top of the container.

• They do not fill the container.

Which of the following is true about the compressibility of gases?

• Gases are always liquid.

• Gases are always solid.

• Gases can be compressed.

• Gases cannot be compressed.

Under what condition can any chemical exist as a gas?

• At any temperature.

• At the right temperature, without chemical breakdown.

• Only at high pressure.

• Only in a vacuum.
