atomic weight  atomic mass

In chemistry, we use the word substance to mean the chemical material of which an object is composed.

An ice cube, for example, is composed of the substance water, and this metal pipe is composed of the substance steel.


rura, rurka  tube, pipe
rura chłodnicy  condenser tube

rura do spalań  combustion tube
rura wlotowa  inlet pipe

rura zasilająca  supply pipe

feed pipe

delivery pipe

rurociąg  pipeline, piping
