particle motion in gases Flashcards
The particles in a gas are
constantly moving with random directions and speeds
If you increase the temperature of a gas what happens?
You transfer energy into the kinetic energy stores of its particles
As you increase the temperature of a gas the average speed
Increases
As gas particles move at high speeds, what do they do
They collide with each other and exert a force and so a pressure on it
In a sealed container the outward gas pressure is the
Total force exerted by all of the particles in the gas on a unit area of the container walls
Faster particles and more frequent collisions both lead to an increase in
net force and gas pressure
If the temperature is constant increasing the volume of a gas means
The particles get more spread out
pressure and volume is what type of proportional
inversely
pressure and volume is what type of proportional
inversely
The pressure of a gas causes a net outwards force at
right angles to the surface of its container
there is a force on the where of the container
outside due to the pressure of gas around it
Doing work on a gas can increase its
Temperature
