Water Vapor and Condensation Concepts

The video explains that water vapor is the gaseous phase of water, which is invisible and present in the air around us. It discusses how water vapor condenses into liquid on cold surfaces and can evaporate back into gas. The video also clarifies that clouds are not water vapor but tiny droplets of liquid water. Overall, it emphasizes that water vapor is a gas.

What is the chemical notation used to indicate that water vapor is a gas?

• A small 's' in parentheses

• A small 'l' in parentheses

• A small 'g' in parentheses

• A small 'aq' in parentheses

Why is water vapor not visible in the air around us?

• Because it is a solid

• Because it is a liquid
