Why does air temperature change as altitude increases?
It get's colder as you travel up into the atmosphere because the ozone layers block away a lot of heat. But once you get to the tropsphere layer te temperature is about 1,600 degrees because the sun goes throught that layer first, and that layer is about 500 kilometer's thick.
Why does the air temperature at different altitudes change?
Well, why does the temperature in different areas change? The same locations can't be the same temperature. Just as the closer to the North and South pole means the temperature will be colder, the higher you are from the ground, the colder it will be, generally speaking. The sun doesn't really do much to warm the air, it warms the ground, and the ground warms the air. That's why the temperature doesn't do a near-instant drop when the sun goes down. Since the ground is the heat source, the higher up, the further from the heat source, and thus the colder it is. With that being said, temperatures can be warmer higher up, due to the fact that the air is constantly moving. Jet streams are very good at transferring warm and cold air, at levels far above the ground. Warmer air will warm the surrounding air, slightly cooling off as the heat exchanges, further contributing to different temperatures at ground level, as well as above it. Of course, the reverse effect happens with cold air; it will cool off the air around it, assuming it is colder than the air, warming up when the heat exchanges. Air temperature changes because of differing air pressures.

Why does relative humidity depend on air temperature?
Relative Humidity is the ratio of the mass of vapour present in a certain volume of air to the mass of water vapour required to saturate the same volume of air at the same temperature. Another way of defining relative humidity is related to dew point. I.e relative humidity=s.v.p at dew point over s.v.p at air temperature multiply by 100%. And dew point is dependent upon prevalent atmospheric conditions like TEMPERATURE,wind and the amount of water vapour in the atmosphere.
Would dew point temperature be close to that of the air temperature if there is heavy fog on the ground?
Yes! In fact, the air temperature and dewpoint should be exactly the same during heavy fog.
Will taking heat out of air raise or lower the temperature?
Taking heat out of air will lower the temperature. Heat energy is responsible for raising the temperature of a substance, so removing heat will result in a decrease in temperature.
Taking heat out of the air will do what to the air temperature?
Removing heat from the air will lower its temperature.
Removing heat from the air will the air temperature?
Removing heat from the air will decrease the air temperature. Heat is what gives particles in the air energy to move and the removal of heat will cause the particles to slow down, resulting in a decrease in temperature.
What is the index that combines air temperature and relative humidity to determine an apparent temperature?
The heat index is the index that combines air temperature and relative humidity to determine an apparent temperature. It measures how hot it feels to the body by taking into account the moisture content in the air, which affects the body's ability to cool itself through sweating. High heat indexes can indicate increased risk of heat-related illnesses like heat exhaustion or heat stroke.
Why temperature decreases when air velocity increases?
When air velocity increases, it promotes more efficient heat transfer between the air and surrounding surfaces. This enhanced convective heat transfer results in the air taking away more heat from the surface, causing its temperature to decrease. Additionally, higher air velocity increases the rate of mixing within the air, ensuring that the cooler air is distributed more evenly.
Why is the temperature of air taken in shade?
Temperature of air is taken in shade to reduce the influence of direct sunlight. Direct sunlight can significantly heat up surfaces which can lead to inaccurate temperature readings. Taking the temperature in shade ensures a more reliable and consistent measurement of the actual air temperature.
What is the relation ship between air -to-air heat pumps heating capacity and outside air temperature?
The heating capacity of an air-to-air heat pump decreases as the outside air temperature drops. This is because the efficiency of heat transfer decreases as the temperature differential between the outside air and desired indoor temperature increases. As a result, the heat pump has to work harder to extract heat from the outside air, leading to a decrease in heating capacity.
Why is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.
How is temperature diffrent from heat?
Heat is the cause and temperature is the effect. Heat is energy but temperature is outcome of storage of such heat energy in a body. If same amount of heat is given to the same mass of water and aluminium, then temperature will be more in aluminium but less in water. This is similar to the collecting air in different containers. Air is equivalent to heat and pressure created is equivalent to temperature.

What is the difference between heat and air?
heat is hot, air is cold Heat and air differ in every respect; heat is a form of energy that is transferred by a difference in temperature, and air is a mixture of gases.
If the coolant in an air conditioner has a lower temperature the the air in a building then?
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.
