Air temperature and relative humidity

In summary, people are able to spend time in sauna rooms with temperatures over 90° C and low humidity, but would be severely burned in liquid water at the same temperature. This is because in saunas, people can cool themselves by sweating and the low humidity aids in heat dissipation. However, in liquid water, the lack of air and high heat conductivity would cause severe burns in less than a minute, even at the same temperature as the sauna.

In sauna rooms, people spend time in conditions of air temperature over 90° C (194° F) with a relative humidity near 10%. However, if you stick your arm into liquid water that is at a temperature of 90° C (194° F), you will be severely burned in less than one minute. Give two reasons why people are able to spend time in a sauna, but are severely burned in water at the same temperature.

I have no idea why this is! Help?

Which has more heat? A sauna with a relative humidity of 10% or a bucket of water, both at the same temperature, 90 C?

You can cool yourself in a sauna by sweating. If you were wearing a coat in a sauna you would probably over heat and die.
 

What is the relationship between air temperature and relative humidity?

The relationship between air temperature and relative humidity is that as the air temperature rises, it can hold more water vapor, resulting in a decrease in relative humidity. Conversely, as the air temperature drops, it can hold less water vapor, resulting in an increase in relative humidity.

How is air temperature and relative humidity measured?

Air temperature is typically measured using a thermometer, while relative humidity is measured using a hygrometer. These instruments can be found in weather stations or can be purchased for personal use.

What is the ideal air temperature and relative humidity for human comfort?

The ideal air temperature for human comfort is typically between 68-78 degrees Fahrenheit (20-25 degrees Celsius). Relative humidity should ideally be between 30-50% for optimal comfort. Higher humidity levels can make the air feel warmer and more humid, while lower humidity levels can make the air feel cooler and drier.

How does air temperature and relative humidity affect plant growth?

Air temperature and relative humidity can greatly impact plant growth. High temperatures and low humidity can lead to increased evaporation and transpiration, causing plants to lose water and become stressed. On the other hand, low temperatures and high humidity can lead to fungal growth and disease in plants. The ideal conditions for plant growth vary depending on the type of plant, but typically a combination of warm temperatures and moderate humidity is most beneficial.

What are some factors that can affect changes in air temperature and relative humidity?

There are many factors that can affect changes in air temperature and relative humidity, including geographic location, time of day, elevation, and weather patterns. Human activities such as heating and cooling systems, deforestation, and urbanization can also impact air temperature and relative humidity. Natural phenomena such as El Niño and La Niña can also cause fluctuations in temperature and humidity levels.
