return air temperature

Increase in air temperature - popularly called as global warming - refers to mean temperature of entire globe averaged over all months and all places. Hence, the change in temperature at a place, in a particular month, may or may not match closely with chang..

Dry Air - We know that there is water vapour in air. In other words, air contains moisture and so it is wet. This quality of wetness is referred to as humidity. For our physical comfort, humidity should not be too high or too low. Usually when the atmospheric temp..

. Ozone absorbs the ultraviolet radiation and while doing so breaks down into nascent oxygen (O) and oxygen gas O 2..

Nitric acid can also be prepared entirely from the air. Air free from moisture and carbon dioxide is subjected to an electric arc whose temperature is around 3000 o C. At this temperature, nitrogen and oxygen of the air combine to form nitric ..

. Carbon dioxide turns limewater Milky white, so does air. Thus, as each constituent of air retains its own property, it exhibits the property of one or all of its constituents. c) There is no sign of any chemical change when air is formed by mixing the different const..

>The capacity of air to retain water vapour increases with increase in temperature. A rise in temperature causes the rate of evaporation to increase. Thus, many coastal areas have a higher percentage of humidity in summer than in winter. The mass of water vapour presen..

We know that without air, we cannot burn anything. In the laboratory, if the flame of a spirit lamp is to be put out, we just place the lid of the spirit lamp on it (Fig.5.1..

The thermometer shows the suitable air temperature for planting Broccolli. What temperature (in °F) does the thermometer read? => 40°F or 50°F or 15°F or 60°F..
