Leigh's comment about "larger volumes and pressures"
brings to mind the benefit (for conceptual
understanding) of presenting pressure as energy per
unit volume. Or, more precisely, as the integral of
PdV. Over "inflating" a truck tire with water presents
very little hazard b/c the dV is infinitesimal, but
over-inflating with air creates a bomb of sorts. Not
much energy stored in the water case, LOTS in the air
case.

there CYA signs on air hoses now in the US?Just what is a "CYA sign" ? On what part of the

Thanks.
