What is ambergis?

Ambergis is a solid, waxy material produced in the sperm whale and in the pygmy sperm whale. Ambergis is formed in the rectum of the whale by indigestible objects from animals on which it feeds (like beaks of squid and cuttlefish). The ambergris is usually released when the whale dies. When released, it is pale white and soft with a strong smell quite like cow manure. Over time and exposure to the elements, ambergis oxidizes, becomes darker in colour and loses its unpleasant odour. It is used in the manufacture of perfume. Ambergis is found in lumps, ranging from 15 gm to 400 kg.

Why is sea water very high in salt content?

The average salinity of sea water is about 3.5%. One cubic mile of sea water contains 166 million tonne of salt. The salts of the sea come from the breaking up of rocks and gradual wearing away of mountains releasing salts that are washed down by rainwater. It is estimated that more than 400 million tonne of dissolved salts are brought to the sea every year by 27,000 cubic km of water. The second source of salt is rocks beneath the ocean bed. There has been a constant slow addition of sea salinity due to evaporation from the ocean surface, combined by discharge from land.

Is rain water completely pure?

Rain water is considered the purest form of water. Impurities and salts present in water on earth are left behind during vaporisation by the sun. However, the rain water we receive on earth is not necessarily pure, as it brings down impurities and particles present in the atmosphere along with it.

Why do we blink when a hammer strikes metal?

Blinking, apart from cleaning and lubricating the soft tissues of eyes, also serves as a protective way of keeping things away from entering the eyes, by lowering the eyelids and lashes for protection. Blinking is a reflex action and happens automatically, as soon as the brain perceives a threat. The striking of hammer is taken as a threat by the brain. There are multiple muscles that control the reflex action of blinking.

What is administratium?

It is a spoof on administration. Its official definition: Administratium is the heaviest element known to science and was recently discovered at a major US research university. The element has no protons or electrons and thus, has the atomic number 0. However, it does have one neutron, 125 assistant neutrons, 75 vice-neutrons and 111 assistant vice-neutrons, which gives it an atomic mass of 312. These 312 particles are held together by a force that involves the continuous exchange of meson-like particles called morons. Since it has no electrons, administratium is inert. However, it can be detected chemically as it impedes every reaction it comes in contact with.

If the density of gold is more than that of iron, why is gold softer than iron?

The softness of a metal is its ability to undergo permanent deformation under applied stress. All metals have specific crystalline structures. Each structure has its own densely packed crystalline planes. There exist line defects and plane defects in a crystal system. Such defects are more in densely packed crystal systems, i.e., metallic crystals with higher density, and result in a number of slip planes, which can easily deform under a little stress. Noble metals like platinum, gold and silver have extra slip planes called twinning. Iron and most of its alloys have very rigid and open packed crystal structures and are difficult to deform.
