So when you hear a weather forecaster say, "It's 85 degrees outside, but with the humidity, it feels like 92 degrees," that 92 is the combination of the temperature and the dew point, also known as the heat index. As a quick rule of thumb, the closer the dew point is to the ac...
Explain why the rate of transpiration is reduced when humidity is high. 1. Explain how heat is transferred by the following mechanisms: a. Conduction b. Convection c. Radiation 2. a. Explain why heating an air mass causes it to rise. b. What is latent heat? Explain w ...
Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the poss...

But it required careful planning — the temperature, humidity (湿度) and lighting all had to be just right. The cloud only lasted for a short while, though. Wingsuits The suit realizes your dream of flying like a bird. Well, not exactly flying, but gliding (滑翔) through the air. It ...
000 a day and has implemented a rehabilitation and protection program in the area, constructing large groups of wetlands and lakes at the foot of the Yulong and making artificial snow on a regular basis to increase humidity that decreases temperature and slows melting. Vegetation in the area was...
That combination of temperature and humidity at which the person’s core temperature starts to continuously rise is called the “critical environmental limit.” Below those limits, the body is able to maintain a relatively stable core temperature over long periods of time. Above those limits, core...
Why does vapor pressure increase with temperature? Why does humidity decrease transpiration? Why evaporation of water is a physical change? Why is water vapor concentration on the rise? Why does the temperature increase in the stratosphere?
Benefits: consistent, powerful cooling performance, largely independent of the ambient temperature and humidity. Many compressor air conditioners integrate a heating system. The performance and efficiency of such heating systems depend on what type you have. If you have a simple heating resistor the ...
Why does humidity decrease transpiration? How does precipitation work in the water cycle? What causes condensation? Why does water move into the ground to create groundwater? Why does the level of water seem to not rise when salt is dissolved in water?
