At the time of inspiration diaphgram and external intercoastal muscle contracts leading to increase in thoracic volume. Also, ribs move outward and sternum moves upward.

Aluminium sulphate which is given by the chemical formula Al₂(SO₄)₃ is used for making fireproof clothes and it is also used as a fire fighting foam. Aluminium sulphate is also used as an antiseptic, astringent and also as a modern in dyeing textiles.

The chemical formula of alumina is Al₂O₃ and that of anhydrous aluminium chloride is AlCl₃. Alumina is nothing but aluminium oxide. Anhydrous aluminium chloride is prepared by heating a mixture of alumina and carbon in a current of dry chlorine.

K₂SO₄.Al₂(SO₄)₃.24H₂O, Na₂SO₄.Al₂(SO₄)₃.24H₂O, (NH₄)₂SO₄.Al₂(SO₄)₃.24H₂O and (NH₄)₂SO₄.Fe₂(SO₄)₃.24H₂O are respective chemical formulae of Potash alum, sodium alum, ammonium alum, and ferric alum.

The MKS system uses the same fundamental units as the SI system. It uses meter for distance, kilogram for mass, and second for time. These are all present as fundamental units in the SI system.

AS plane angles are measured in radians, in the same way solid angles are measured in steradians. A solid angle can be interpreted as the 3-dimensional form of a plane angle.

MKS stands for meter-kilogram-second. CGS stands for centimeter-gram-second. SI stands for System international. Decibel is a unit of sound intensity.

1 Mega Joule = 1000000 Joules. Therefore 89 Mega Joules = 89000000 Joules.
