Textbook Problem

# Put the following in order of increasing pressure: 363 mm Hg, 363 kPa, 0.256 atm, and 0.523 bar.

Interpretation Introduction

Interpretation:

The given pressures should be arranged in their increasing order.

Concept Introduction:

Pressure=ForceArea

Pressure can be expressed in different units. But it is normally reported in mmHg(millimetersofmercury)

General unit conversions:

1atm=760mmHg1pascal=1newton/meter21atm=760mmHg=101.325kilopascals=1.01325bar1bar=1×105pascal

Explanation

Given the values of pressure as 363â€‰mmâ€‰Hgâ€‰,â€‰363â€‰kâ€‰Paâ€‰,â€‰0.256â€‰atmâ€‰,â€‰0.523â€‰bar

• Pressure =â€‰363â€‰mmâ€‰Hg
• Conversion of kâ€‰Pa into mmâ€‰Hg:

Givenâ€‰thatâ€‰pressureâ€‰=â€‰363â€‰kâ€‰Pa760â€‰mmâ€‰Hgâ€‰=â€‰101.325â€‰kilopascals

Â Â 363â€‰kâ€‰Paâ€‰â€‰Ã—â€‰760â€‰mmâ€‰Hg101.3â€‰kPaâ€‰=â€‰2723.3â€‰mmâ€‰Hg

• Conversion of atmâ€‰intoâ€‰mmâ€‰Hg.

Givenâ€‰thatâ€‰pressureâ€‰=â€‰0.256â€‰atm

1â€‰atmâ€‰=â€‰760â€‰mmâ€‰Hg0.256â€‰atmâ€‰Ã—â€‰760â€‰mmâ€‰Hg1â€‰atmâ€‰=â€‰194.56â€‰mmâ€‰Hg

• Conversion of barâ€‰intoâ€‰mmâ€‰Hg
