Kinetic Theory f Gasses
Exam Update Solution 2023
what is absolute zero - Answer-absolute zero is the point where particles are no longer
moving at
... [Show More] all. they cannot get any more 'still'
what temperature is absolute zero in degrees c - Answer--237oc
what temperature is absolute zero in kelvin - Answer-0 K
what does particle theory state in relation to pressure - Answer-it says that colliding gas
particles create pressure
How do colliding gas particles create pressure? - Answer-They bang into each other
and anything else in the way, When they collide with something they exert a force on it
and their momentum and direction change. in sealed container this creates outward
pressure.
how is energy in particles related to temperature - Answer-the temperature of a gas in
kelvins is proportional to the average energy in the kinetic energy store of its particles
what is the freezing point of water in kelvins - Answer-273 K
what is the boiling point of water in kelvins - Answer-373 K
why does temperature stay constant when changing state - Answer-because for a short
period of time all the energy is used to break or build the bonds between the particles
instead of increase the temperature. after this has happened temperature can inc. or
dec.
what does pressure created by gasses depend on - Answer-how fast the particles are
moving and how often they hit the 'walls' of a container
why does increasing the temperature increase the pressure created by gasses -
Answer-because the particles hit the container walls harder and more frequently due to
having more energy resulting in a larger force, creating more pressure.
How does volume affect pressure? - Answer-increasing the volume decreases the
pressure and vice versa
why does increasing volume decrease pressure and vice versa - Answer-because if you
put the same amount of gas in a bigger container the pressure will decrease as there
will be less collisions between particles and wall. when the volumes reduced particles
hit the wall more frequently.
