The kinetic theory of matter is one of the models that scientists use to help them to make sense of the world around them. The word kinetic always suggests something is moving, and this theory is about the movement of particles in solids, liquids, and gases. Particles transfer heat energy into kinetic energy.
Only gases
Only solids
Liquids and gases
All of them
Covering the liquid with a beaker
Making sure that there were no draughts
Spreading it out over a larger area
All of the above
Mercury is a metal so it conducts heat into the thermometer
Mercury behaves in an unusual way
Particles of liquids expand when they are heated and contract when they are cooled so the mercury fills more or less of the thermometer depending on the temperature
The particles move faster or slower depending on the temperature so the mercury expands and contracts
When the particles of the water vapour hit the window, they stick to it
The particles lose energy to the cold surface, slow down and become closer together
The particles clump together because of the light coming through the window, forming water
The particles speed up, forming water droplets
The gas explodes
The pressure of the gas increases
The gas implodes
The gas condenses
Heat naturally goes upwards
It is pushed there by the cold air
It is less dense than colder air
It doesn't, this is a myth
It will expand
It will contract
It will burn
It will explode
The faster particles escape leaving the slower particles behind
There are fewer particles
Evaporation needs a breeze and breezes cool things down
It has a smaller volume than before
Some of the fluid escapes from the particles so they are lighter
Their particles are closer together
Hot particles lose their quarks and become lighter
Their particles are further apart
Vibrating more slowly than when the solid was cool
Vibrating more rapidly than when the solid was cool
Moving around more slowly than when the solid was cool
Moving around more rapidly than when the solid was cool
