What is relationship between relative humidity and temperature?
There is an effect if you're a living being and trying to cool down. Humidity does not change the temperature. It will make it difficult for your body to cool down, so it 'feels' hotter with humidity. Sweat has to evaporate for your body to cool down. It's harder to evaporate when the air is already saturated with water (ie high humidity).
Why relative humidity increases as temperature decreases and vice versa?
"Relative" humidity means how much water vapor there is in the air compared tohow much the air could hold at that temperature.And warmer air can hold more water vapor. Cooler air can hold less.So ... if there's a certain amount of water vapor in the air, and the air temperaturedrops, the air can now hold less at the reduced temperature, so the amount that'sthere is now a greater fraction of how much the air could hold ... higher relativehumidity.See the link below for the formula of Buck; the effect of temperature is evident.
What effect takes place when relative humidity increases or decreases while calibrating the instruments?
When relative humidity increases during instrument calibration, it can affect the accuracy of measurements by causing sensors to react differently than in normal conditions. Decreasing relative humidity can also impact instrument calibration by changing the thermal properties of materials, which can alter sensor response. Overall, it's important to maintain stable environmental conditions during calibration to ensure accurate and reliable results.
How you would use a wet bulb thermometer and a dry bulb thermometer to find a hr relative humidity?
To find relative humidity using a wet bulb and dry bulb thermometer, first measure the temperature with both thermometers. The dry bulb thermometer provides the air temperature, while the wet bulb thermometer, which is moistened and exposed to airflow, measures the cooling effect of evaporation. Using the readings from both thermometers, you can refer to a psychrometric chart or use a formula to calculate the relative humidity based on the difference in temperatures. The smaller the difference between the two readings, the higher the relative humidity.
When is your highest relative humidity?
AnswerIt's 78C of heat index recorded at Dharhan Saudi Arabia in 2000 with a 41C and over 70% humidity rate.
Three factors that effect the rate of evaporation?
Three factors that affect the rate of evaporation are temperature (higher temperature increases evaporation rate), humidity (lower humidity increases evaporation rate), and surface area (larger surface area increases evaporation rate).
What effect does evaporation have on the relative humidity at a given temperature?

Which of these have an effect on air pressure?
Temperature, altitude, and humidity all have an effect on air pressure. As temperature increases, air pressure decreases, while air pressure decreases with increasing altitude. Humidity can also affect air pressure by directly influencing the density of the air.

What has the greatest effect on humidity?
Temperature has the greatest effect on humidity. Warmer air can hold more water vapor, so as temperature increases, the air can hold more moisture, leading to higher humidity levels. Conversely, as temperature decreases, air becomes less capable of holding moisture, resulting in lower humidity levels.
Name three things that effect air pressure?
temperature, water vapor, and elevation.
How does temperature affect humidity?
Temperature does have a direct effect on relative humidity. ( just to make the water vapor move faster when war and slower when cool). As temperature goes up, the ability of the air to hold more gas goes up, so relative humidity goes down (unless more water vapor is being added). very good answer if you don't trust it. i got an A on a take home test with this answer Temperature affects humidity when they take place in the Dew point when water vapour changes to liquid. At this temperature humidity is high. The higher the temp, the more water vapor can be carried in air. Thus if you heat air (as is done in the winter) the relative humidity drops ... the air seems dryer even though the total amount of water vapor is unchanged.

What happens to the relative humidity when temperature decreases but the amount of water vapor in the air stays the same?
The relative humidity percentage wil continue to rise until the dew point is achieved (100% relative humidity). This is when the proper pressure conditions are correct for the water particles in the air to accumulate causing the effect most know as "morning dew".
What is a pyschometer?
A psychrometer is a type of hygrometer used to measure the relative humidity in the air. It consists of two thermometers, one with a dry bulb to measure air temperature, and the other with a wet bulb covered in a water-soaked cloth to measure the cooling effect of evaporation. By comparing the temperature readings of the two bulbs, the relative humidity of the air can be determined.
What is the effect of temperature on the viscosity of gases?
For liquids; Viscosity tends to fall as temperature increases. For gas; Viscosity increases as temperature increases.
