Chapter 5, Problem 5.13QP
Interpretation Introduction

Interpretation:

The unit of mmHg has to be converted into atm, torr, and kPa.

Concept Introduction:

Standard atmospheric pressure: Standard atmospheric pressure is equal to the pressure that supports a column of mercury exactly 760 mm (or76cm) high at 0oC at sea level.

Unit conversion of pressure:

1 torr = 1 mmHg1 atm = 760 mmHg         = 760 torr

Relation between atmospheres and Pascal is,

1 atm = 101,325Pa         = 1.01325×105Pa (or)1.01325×102kPa
