solids, liquids and gases
-
evaporation
the escape of molecules with higher energy from the surfaces of liquids. after they escape,, the remaining molecules have a lower average kinetic energy which means the temperature is lower
to increase the rate of evaporation, increase the rate of evaporation, increase temperature, surface area or provide a draught
-
density practical
measure mass then volume if a regular shape by multiplying length, width and height, or using a eureka can and measure the volume of water displaced then calculate density using the equation
motion and pressure
as gas particles move randomly they collide with the walls of the container, producing a net force at right angles to the wall. therefore a gas at higher pressure has more frequent collisions with a greater force
-
absolute zero
at -273 degrees celcius, the particles no longer move so they have no kinetic energy
absolute zero is OK so to convert from celcius to Kelvin you need to add 273 and vice versa for converting in the other direction
