What is a Catalytic Converter?

-
A catalytic converter is used to reduce the amount of harmful gases pumped into the atmosphere by vehicles. The converter is a metal case containing a metal or ceramic in the shape of a honey comb which is coated with a precious metal like platinum or rhodium which acts as a catalyst. The converter is fixed into the exhaust pipe of the vehicle. As the engine's exhaust gases flow through the honey comb, the catalyst converts the harmful gases like carbon monoxide, oxides of nitrogen and hydrogen into water vapour and carbon dioxide.

Why do Howler Monkeys Howl?

-
Image
T he howler monkeys are found in the rainforests  of South America. The deep howls of these monkeys echo around the forest at dawn and dusk. A bony box in the thick neck of these monkeys amplifies its howling calls. They make the noise to warn other howler monkeys to keep out of the family group's patch of forest, so that they can keep the food supplies there for themselves.

Meteorites are bodies (a lump of stone or metal) from space that are large enough to reach the ground without burning up in the atmosphere. The largest known meteorite weighed about 60 tones and landed in Namibia , Southern Africa. Meteorites were probably formed at the same time as the Solar System. A falling meteorite leaves a brilliant trail in the sky known as a fireball. Some meteorites are mostly metal (iron and nickel ) while others are made of stone.

Why do Some Ants Live in Thorn Bushes?

T o keep plant-eating animals away, the whistling thorn bush has an armoury of sharp thorns. However, it is a home to virulent ants which keep off plant eating insects. They live in large swollen bulbs that develop at the bases of thorns. They attack in hordes by biting and stinging if any browsing animal dares to venture near the plant to try and eat leaves. They also keep a check on caterpillars , aphids and other plant eating animals and are, in return, rewarded by the plant. They feed upon the fruits growing on leaf tips and also get a sugary drink from the leafstalks.

Quantum Theory Full Documentary HD https://www.youtube.com/watch?v=A-iB5iEy2Kc&t=1183s quantum hypothesis Posted by: Margaret Rouse Contributor(s): Ivy Wigmore Quantum hypothesis is the hypothetical premise of current material science that clarifies the nature and conduct of issue and vitality on the nuclear and subatomic dimension. The nature and conduct of issue and vitality at that dimension is at times alluded to as quantum material science and quantum mechanics. In 1900, physicist Max Planck introduced his quantum hypothesis to the German Physical Society. Planck had tried to find the reason that radiation from a sparkling body changes in shading from red, to orange, and, at last, to blue as its temperature rises. He found that by making the suspicion that vitality existed in individual units similarly that issue does, instead of similarly as a steady electromagnetic wave - as had been once in the past accepted - and was consequently quantifiable, he could...
