WY DIES mater boil IN ueSSel on NefyeI
Because the parts of the liquid next the fire get
heated and rise up throus the colder parts v''lch
are heavier and this Is found to be the principal
manner of communicating heat to all parts OF IL
quid for, if the heat is applied at the top, IT can
only with great difficulty be conducted through
the liquid either sideways or downward5; but
when applied below. the parts, as they are heated
become enlarged and lighter they raise to the top,
ana heat the others in their progress, while those
others, being still somewhat heavier, sink down,
and are heated fully in their turn. BY degrees the
whole liquid gets hot that the parts next the bot
tom are converted into steam CT vapour, which IFS
es through the rest of the liquid IN bubbles to the
top, and there flies off till the whole liquid is eva
porated
