It would depend on the air temperature inside the classroom. There are differences in data, but generally, experts with Energy Star and the Consumer Products Safety Commission agree that 40 percent is considered to be an acceptable relative humidity point. The CPSC says this is the minimum (and below that a humidifier should be used) while this is in the middle of what Energy Star recommends (between 30 and 50 percent). Regardless, a room should never be above 60 percent as mold and bacteria grow easier above 60 percent relative humidity.

What are facts about relative humidity?
Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
What type of air has a realative humidity of 100 percent?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
What does humidity above 50 percent mean?
Humidity above 50 percent indicates a higher amount of water vapor in the air relative to its maximum capacity at that temperature. This can make the air feel damp and can affect how comfortable or uncomfortable it feels. High humidity levels can also contribute to the growth of mold and mildew.
What are relative humidity of the locations from highest to lowest?
The relative humidity of locations can vary depending on the weather conditions, but generally, locations closer to the equator tend to have higher relative humidity levels. Coastal areas also usually have higher humidity compared to inland locations. Conversely, arid regions and high-altitude locations typically have lower relative humidity.
Does evaporation take place when relative humidity is high or low?
Evaporation takes place when relative humidity is low because the air has a higher capacity to hold water vapor. When relative humidity is high, the air is already saturated with water vapor, making it difficult for additional moisture to evaporate.
What does a relativly humidity of 75 percent mean?
A relative humidity of 75 percent means that the air is holding 75 percent of the maximum amount of moisture it can contain at a given temperature. This indicates that the air is quite humid, which can make it feel warmer and more uncomfortable. When relative humidity reaches this level, condensation may occur, leading to the potential for dew or fog. High relative humidity can also affect drying processes and increase the risk of mold growth.
What is the relationship between high relative humidity and the feeling of discomfort in summer?
relative humidity causes heat and therefore discomfort
What are facts about relative humidity?
Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
What is the approximate relative humidity inside a cloud?
The relative humidity inside a cloud is typically close to 100%. Clouds form when air is saturated with water vapor, so the relative humidity is high.
What type of air has a realative humidity of 100 percent?
That would be "dewpoint"...When the air temperature falls to the dewpoint (or dewpoint rises to the air temperature), then you have 100% relative humidity.
It is 95 degree's in the hopi desert is the relative humidity likely to be high or low?
It could be either, but usuall high humidity.
What does it mean to have relative humidity of 90 percent?
A relative humidity of 90 percent means that the air is holding 90 percent of the maximum amount of moisture it can contain at a given temperature. This high level of humidity often makes the air feel muggy or oppressive and can lead to discomfort. It also increases the likelihood of condensation, which can result in dew, fog, or precipitation. In such conditions, sweat may not evaporate effectively, reducing the body's ability to cool itself.
When using a psychrometer and the two temperatures read nearly the same you can conclude that?
the air has a high relative humidityThe air has a high relative humidity
When the relative humidity of the air is reported as being high then what do we feel?

Is 66 percent humidity high?
yes !
What does humidity above 50 percent mean?
Humidity above 50 percent indicates a higher amount of water vapor in the air relative to its maximum capacity at that temperature. This can make the air feel damp and can affect how comfortable or uncomfortable it feels. High humidity levels can also contribute to the growth of mold and mildew.
