Matter - Part 1 Flashcards
How is average kinetic energy related to temperature?
• higher temperatures results when molecules collide with each other at faster speeds (faster molecules, higher temperature and more molecular energy)
Absolute zero
- All motion stops at 0 degrees Kelvin
* it was determined by studying trends in data of gas volume and temperature
Assumptions of the kinetic theory and when they fail
The paths of uninterrupted travel of particles in a gas are relatively short because the particles are constantly colliding with each other or with other objects
• fails if the temperature is low, and if the pressure is high
What kind of pressure is measured with a barometer?
Atmospheric pressure
Gas pressure results from the force exerted by a gas particle per…
Unit surface area of an object
Additionally, gas pressure is the simultaneous collisions of billions of particles in a gas with an object
Charles law
V1/T1=V2/T2
Boyles law
P1V1=P2V2
Combined Gas Law
P1V1/T1=P2V2/T2
Gay’s law
P1/T1=P2/T2
Ideal gas law
PV=nRT
In order to increase the boiling point of water
You need to increase the outside pressure
