Textbook Question

A tank contains oxygen (O₂) at a pressure of 2.00 atm. What is the pressure in the tank in terms of the following units? b. lb/in.²

Verified step by step guidance

Identify the given pressure in atmospheres: 2.00 atm.

Recall the conversion factor between atmospheres and pounds per square inch (psi): 1 atm = 14.696 psi.

Multiply the given pressure in atmospheres by the conversion factor to convert to psi: Pressure in psi = 2.00 atm * 14.696 psi/atm.

Set up the multiplication: 2.00 * 14.696.

Perform the multiplication to find the pressure in psi.

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. Common units for pressure include atmospheres (atm), pounds per square inch (lb/in²), and pascals (Pa). Understanding how to convert between these units is essential for solving problems related to pressure in different contexts.

Unit Conversion

Unit conversion involves changing a measurement from one unit to another while maintaining its value. For pressure, converting from atmospheres to pounds per square inch requires knowing the conversion factor, which is 1 atm = 14.696 lb/in². This concept is crucial for accurately expressing pressure in the desired units.

Gas Laws

Gas laws describe the behavior of gases under various conditions of pressure, volume, and temperature. While this question focuses on pressure conversion, understanding the ideal gas law (PV=nRT) can provide context for how pressure relates to other properties of gases, which may be relevant in broader applications.
