1564 - What is the relationship between the amount of water vapor in the air and humidity.

The amount of water vapor in the air is directly related to humidity. Humidity is a measure of how much water vapor is in the air. When there's more water vapor in the air, the humidity is higher. Similarly, when there's less water vapor, the humidity is lower.

Think of it like a jar that can hold a certain amount of water. If the jar is full of water, it's like high humidity. If the jar is almost empty, it's like low humidity. So, the amount of water vapor in the air is what determines the humidity.
