Humidity and dew Point

Front

What is dew point?

Back

The temperature at which air's water vapor capacity is exactly full.

Front

What is relative humidity?

Back

The amount of water vapor in the atmosphere compared to how much it could hold.

Front

What is humidity?

Back

The amount of water vapor in the air.

Front

What causes humidity in the air?

Back

The sun heats up surface water, causing evaporation, which creates humidity.

Front

What is an accurate relative humidity reading?

Back

45%.

Front

What happens when air reaches its dew point?

Back

It can no longer hold all the water vapor, leading to condensation.

Front

What is the relationship between temperature and humidity?

Back

As temperature increases, the air can hold more water vapor, increasing humidity.

Front

What is absolute humidity?

Back

The total mass of water vapor present in a given volume of air.

Front

What is the difference between relative humidity and absolute humidity?

Back

Relative humidity is a percentage of how much water vapor the air holds compared to its capacity, while absolute humidity is the actual amount of water vapor in the air.

Front

What is the role of evaporation in humidity?

Back

Evaporation adds water vapor to the air, increasing humidity.
