Gas

The video explains the behavior and properties of gas particles, highlighting their random motion and higher energy compared to liquids and solids. It discusses how gases fill containers, can flow, and be compressed. The video also notes that any chemical can exist as a gas at the right temperature, provided it doesn't decompose first.

What characteristic of gas particles allows them to fill any container they are placed in?

• Their solid state

• Their random motion

• Their low energy

• Their fixed shape

Why do gas particles have more energy compared to liquids and solids?

• They are heavier

• They are closer together

• They are in constant random motion

• They are colder

Which of the following is a property of gases?

• They are always visible

• They can flow

• They have a definite volume

• They cannot be compressed

Under what condition can any chemical exist as a gas?

• When exposed to sunlight

• At the right temperature

• When mixed with water

• At a high pressure

What happens to a chemical if it decomposes before becoming a gas?

• It remains a solid

• It turns into a liquid

• It cannot exist as a gas

• It becomes more stable
