above sea level is
exactly 1 mile. Which
of the following would
explain why water
boils at a lower
temperature in Denver
than at sea level?
The air pressure in
Denver is lower, and
this lower air
pressure causes the
boiling point to be
lower than sea level.
The air pressure in
Denver is higher,
and this extra
pressure pushes the
boiling point lower.
The higher elevation is
further from the
