unit 2, atmosphere humidity and clouds honors

Front

What phase change is condensation?

Back

Gas to liquid.

Front

What is the equation for relative humidity?

Back

RH = specific humidity / capacity x 100.

Front

Why do you feel hotter on a humid day than on a dry day?

Back

High humidity reduces evaporation of sweat, leading to discomfort as sweat cannot evaporate effectively, causing a sticky feeling.

Front

What is orographic lifting?

Back

When air is forced to rise when it hits a mountain, leading to cooling and condensation, often resulting in clouds on the windward side.

Front

What is a cloud?

Back

A collection of very fine water droplets or ice particles suspended in the atmosphere; clouds are a form of condensation.

Front

What is the difference between specific humidity and relative humidity?

Back

Specific humidity is the mass of water vapor per unit mass of air, while relative humidity is the ratio of the current amount of water vapor to the maximum amount possible at that temperature.

Front

What role does temperature play in the capacity of air to hold moisture?

Back

As temperature increases, the capacity of air to hold moisture also increases.

Front

What is the process of evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor, absorbing heat from the environment.

Front

How does condensation occur in the atmosphere?

Back

Condensation occurs when air cools to its dew point, causing water vapor to change into liquid water droplets.

Front

What is the significance of dew point in weather?

Back

The dew point is the temperature at which air becomes saturated with moisture, indicating the likelihood of condensation and cloud formation.
