Pressure in Gases Flashcards
what increases alongside the rise in temperature of a gas
the kinetic energy in the particles of the gas also increase
how do gas particles exert pressure on walls/containers
by colliding with the wall/container
what happens to the momentum and direction of the particle that collides with the wall/container
the momentum changes resulting in the particle bouncing off the wall
the pressure exerted on the wall by a ball is equal to what
the force of the wall per unit area
When gas particles collide with the walls of their container, their momentum changes. Change in momentum are called what
impulses
what’s the equation for momentum
momentum = Mass x Velocity
what happens in a stretchy container like a balloon
An increase of temperature leads to higher kinetic energy of particles.
These particles collide with (hit) the walls of the container with more force.
If the container can expand (increase its volume), it will.
This is because the gas pushes it outwards.
what’s the equation for a fixed mass of gas at constant temperature:
p1 x V1 = p2 x V2.
What two stores of energy are added together to calculate the internal store?
Kinetic Store + Chemical Store = Internal Store
list the three terms that are multiplied together to give the change in thermal energy
1) Mass
2) S.H.C
3) Temperature Change
How does doing work on a gas affect the energy in its kinetic store and its temperature?
1) Kinetic energy will increase
2 Temperature will increase
