Chapter 10, Problem 20b
Perform the following conversions: (b) 0.685 bar to kilopascals
Verified step by step guidance1
Identify the conversion factor between bars and kilopascals. 1 bar is equivalent to 100 kilopascals.
Set up the conversion equation using the given value in bars. Multiply the value in bars by the conversion factor to convert it to kilopascals.
Write the equation: \(0.685 \, \text{bar} \times 100 \, \text{kPa/bar} = X \, \text{kPa}\).
Perform the multiplication to find the value of \(X\).
The result will give you the pressure in kilopascals.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Pressure Units
Pressure is a measure of force applied per unit area, commonly expressed in various units such as pascals (Pa), bars, and atmospheres. Understanding these units is essential for converting between them, as they represent the same physical quantity but differ in scale. For example, 1 bar is equivalent to 100,000 pascals.
