Frequently Asked Questions 

Question 1: What is Kinetic Theory of Gases?

Answer: The Kinetic Theory of Gases is a fundamental theory in physics that explains the behavior of gases based on the motion of their constituent particles, which are typically atoms or molecules. It's a macroscopic model that provides a molecular interpretation of gas properties.

Question 2: What is the relationship between kinetic energy and temperature in the Kinetic Theory of Gases?

Answer: This relationship is crucial for understanding the temperature-pressure relationship in gases and why gases tend to expand when heated and contract when cooled. It also helps explain why gases at higher temperatures have higher pressure, as the gas molecules have greater kinetic energy and collide with the walls of the container more frequently and with more force.
