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? d. kPa

Verified step by step guidance

Identify the conversion factor between atmospheres (atm) and kilopascals (kPa). The conversion factor is 1 atm = 101.325 kPa.

Multiply the given pressure in atmospheres by the conversion factor to convert it to kilopascals.

Set up the equation: Pressure in kPa = Pressure in atm × 101.325 kPa/atm.

Substitute the given pressure (2.00 atm) into the equation.

Calculate the result to find 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, and it can be expressed in various units, including atmospheres (atm), kilopascals (kPa), and others. Understanding the relationship between these units is essential for converting pressure values accurately.

Conversion Factors

To convert pressure from one unit to another, specific conversion factors are used. For example, 1 atm is equivalent to 101.325 kPa. Knowing these conversion factors allows for the correct transformation of pressure measurements between different units.

Ideal Gas Law

The Ideal Gas Law (PV=nRT) relates pressure (P), volume (V), temperature (T), and the number of moles (n) of a gas. While not directly needed for simple unit conversion, understanding this law provides context for why pressure is measured and how it behaves under different conditions.
