Question 9
Question: Why does water boil at a lower temperature at higher altitudes? Answer: Boiling occurs at a point where vapour pressure is equal to the external atmospheric pressure. At higher altitudes atmospheric pressure is much less. Less thermal energy is required to g..
Uses
It has very low co-efficient of expansion and can withstand sudden changes in temperature. Therefore highly suitable for laboratory ware like flasks, beakers and oven proof cook ware..
Forest Resources
Forests are the most important resource of our globe. Naturally formed forests are found in such parts of globe - where the factors of plant growth have been ideal for several centuries. For this reason, they are mostly found in regions of high rainfall and regions of high..
Anthrax
Anthrax is a highly infectious disease caused by the bacterium Bacillus anthracis. It is a disease found commonly in domestic animals such as cows, goats and sheep, but human beings can be infected when exposed to the infected animal. The meat of the infected animal if consumed without be..
Climatic Factors - Wind
Air in motion is called wind. Wind velocity can be measured by an Anemometer. It is an important ecological factor of the atmosphere affecting variously the plant life on flat plains, along sea coasts and at high altitudes in mountain..
Gradients of Biodiversity
Gradients of Biodiversity - Biodiversity varies with change in latitude or altitude. The diversity increases as we move from high to low latitudes (i.e., from poles of equator). In the temperate region, the climate is severe with short growing period for plants while in tropical..

o C under a low pressure. As one goes higher the atmospheric pressure decreases. At about 300 m above sea level water boils at 90 o C. Certain pulses cannot be properly cooked in the open in very high regions as the boiling point of water in these places is too low. These puls..
