If the gas is compressed to a volume of 0.70 m³, and the absolute pressure is raised to a value of 0.80 x 10⁵ pa, the temperature will eventually reach 287.1°C.

Ideal gas equation: PV = nRT

where P is pressure, V is volume, n is moles of gas, R is the molar gas constant and T is the temperature in K.

Since n and R are constant, PV/T = constant

P1 = 0.200 x 10⁵ Pa, P2 = 0.800 x 10⁵ Pa

V1 = 1.50 m³, V2 = 0.700 m³

T1 = 27.0°C = 300.15 K, T2 = ?

P1V1/T1 = P2V2/T1

0.200 x 10⁵ x 1.50/300.15 = 0.800 x 10⁵ x 0.700/T2

Temperature T2 = 560.28 K = 287.1°C

In order to determine absolute pressure, a complete vacuum is used. In contrast, gauge pressure is the amount of pressure that is measured in relation to atmospheric pressure, also referred to as barometric pressure. The average barometric pressure at sea level is 14.7 PSIA, while the absolute pressure of a complete vacuum is 0 PSIA.

Current atmospheric pressure, which is the baseline when measuring gauge pressure, is represented as 0 PSIG. one-day Full vacuum is -14.7 PSIG, or +14.7 PSIV when expressed in terms of vacuum pressure.
