Note
One spelling does two jobs, as with any regular verb: the simple past (the gas expanded) and the participle behind perfect and passive forms (has expanded, was expanded). Because expand works both with and without an object, either pattern is open: the market expanded, or the firm expanded it. Mathematics uses it: an expression is expanded into a longer, equivalent sum of terms, and a fraction is expanded by multiplying top and bottom alike.
