- Particle Motion in Gases
- Relation to Temperature
- increase the temperature of a gas, you transfer energy into the kinetic energy stores of its particles
- the higher the temperature, the higher the average energy
- so as you increase the temperature of a gas,the average speed of its particles increases
- Relation to Pressure
- gas particles move at high speeds --->collide into each other--->they exert a force on it
- in a sealed container, the outward gas pressure is the total force exerted by all the particles in the gas on a unit area of the container walls
- faster particles and more frequent collisions lead to increase in net force and gas pressure
- increasing temperature will increase speed and pressure
- if temperature is constant, increasing the volume of gas means particles get spread out and hit the walls of the container less
- gas pressure decreases
- pressure and volume are inversely proportional.
- pV=constant
- Change in Pressure Causes Change in Volume
- if a container can easily change its size, then any change in these pressures will cause the container to compress or expand due to overall force
