Relative humidity is a measure of the current amount of water vapor in the air compared to the maximum amount it can hold at a given temperature. If only half of the water vapor that the air can hold is present, the relative humidity would be 50%. This means the air is at half of its saturation point for moisture.
Polar air typically has low humidity because cold air has a limited capacity to hold moisture. As the air temperature drops in polar regions, the air becomes drier.
If capacity and specific humidity are the same, it means the air is holding as much water vapor as it can at that temperature. This condition is known as relative humidity being 100%, and any added moisture will result in condensation or fog.
When air is cooled, its ability to hold moisture decreases, leading to condensation forming as the air reaches its dew point. This can cause a relative increase in humidity as the air's water vapor concentration remains the same but its capacity to hold it decreases.
The amount of water vapor in the air compared to what it can hold is expressed as relative humidity. This value is typically represented as a percentage, indicating how much moisture is present relative to the maximum capacity of the air at a given temperature. Warmer air can hold more moisture than cooler air, so relative humidity varies significantly with temperature and weather conditions. For example, if the air holds 50% of its maximum capacity, it is considered 50% relative humidity.
Relative humidity becomes the ratio between the actual amount of water vapor present to the capacity that the air has at a particular moment. Just to be an optimist, if the glass is half-filled, the relative humidity is 50 percent. If the glass is three-quarters filled, the relative humidity is 75 percent.
When the air is filled to capacity with water vapor, it is said to be saturated. This occurs when the air's humidity reaches 100%, and any additional water vapor will result in condensation, such as forming clouds or fog.
Relative humidity is the ratio of specific humidity to the overall capacity. So in this case it is 10/50, or 20 percent.

Yes, heat can lower humidity levels by increasing the air's capacity to hold moisture, causing the relative humidity to decrease.
If the relative humidity is 50 percent, the air is holding half of the maximum amount of water vapor it can hold at that temperature. This means the air is holding 50 percent of the water vapor it could potentially hold.
Relative humidity is a measure of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature. Humidity, on the other hand, is a general term that refers to the amount of water vapor in the air regardless of the air's capacity to hold it.
Humidity means amount of water vapour present in air with respect to total amount of air. Relative humidity means ratio of amount of water vapours per unit volume of air to the capacity of air to held maximum water vapours in unit volume of air, at given air temperature.
