a liquid

A liquid must always be contained in a vessel of some kind If the liquid is heated the vessel expands as well as the Liquid, and the observed or apparent increase in volums of the liquid is equal to the difference between the actual or absolute expansion of the liquid and that of the vessel,

The real labsolute) coefficient of expansion of a liquid le defined as the actual or tre increase in volume of unit volume when the temperature increasen by one degree,

The apparent coefficient of expansion af

a liquid is defined as the observed increase in volume of unit volume when the temperature increases by one degree.

Thus the apparent coefficient does not take into account of the expansion endured by the container and it should by obviously lis than the real coefficient.

GENERAL ENGLISH

PUNCTUATION (Contanusd)

The Sema-colon is used:

(a) To separate co-ordinate sentences when a con

THE SUICIDE CLUB) To separate the clauses of a Compound sen-} tence which is joined by a word such as therefore, however, nevertheless, besides. also, otherwise, and so, It is because these words join sentences but are stronger than conjunctions like 'and', and so need a stronger punctuation mark:
