Answer:

The gage and absolute pressures are 900 and 1001 kilopascals, respectively.

Step-by-step explanation:

The gage pressure (
P_(g)), in kilopascals, is the difference between absolute (
P_(abs)) and atmospheric pressures (
P_(atm)), measured in kilopascals. If we know that
P_(g) = 900\,kPa and
P_(atm) = 101\,kPa, then the gage and absolute pressures are, respectively:


P_(g) = 900\,kPa


P_(abs) = P_(atm) + P_(g)


P_(abs) = 101\,kPa + 900\,kPa


P_(abs) = 1001\,kPa

The gage and absolute pressures are 900 and 1001 kilopascals, respectively.
