The directions in which particles in a substance move are random. This is true of solids, liquids and gases.
The higher the temperature, the faster the particles vibrate in a solid or move past each other in a liquid or gas.
Energy needs to be transferred to an object to raise its temperature.
For two identical objects, the one at a higher temperature has more energy.
For two objects made of the same substance at the same temperature, the one with more particles has more energy.
