When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

the particles move slow
What happens to the particles of evaporation?
They float into the atmosphere .
What happens to the particles of matter during a phase change?
The particles change mean speed and concentration.
What happens to the particles of an object as it heats up?
nothing
What happens to the motion of the particles when you move the slide from cold to warm and then from warm to hot?
If the particles are small enough, they will move faster as they get hotter.
What happens to the average energy of the particles in milk when the milk is taken from the refrigerator and begins to warm up?
the average energy of the particles in the milk goes up and the particles move faster when it is removed from the fridge and begins to warm up.
What happens to gases when you warm them?
in a gas the particles are allready spaced out quite alot but when you heat them they get more energy so the fly around more. this heat makes the particles rise but once the fall they fall down.
How does a radiator warm up a room by convention?
warm air particles slowly pass heat energy to all the other air particles
What happens to the particles at absolute zero?
The particles freeze.
Why does metal expand when warm?
Because the particles
Why are there more cold particles than warm particles on one side when trying to find thermodynamic equilibrium?
There are more cold particles than warm particles because the particles attract to frozen temperatures. They do this because since the colder the temperature is usually tight the molecules tighten and there is room for only the particles to squeeze.
What happens to the particles of solute?
It all depends on the particles and the solution
What happens to energy particles when they are frozen?
the particles move slow
Explain how a radiator in a room is able to warm the whole room?
warm air particles slowly pass heat energy to all the other air particles
Warm and moistens airfilters dust particles?
The mucus
How sand traps warm?
because of the sand particles
