There are many ways that prove that the particles of matter are in continuous motion. The one I describe here is very simple to perform.
materials required: incense stick and a match box
procedure:
- put an unlit incense stick in a a corner of room
- now light up the incense stick.
observation: the smell of the unlit incense stick can be observed only by going close to it but the smell of lighted incense stick can be observed from a distance
conclusion:all the particles of matter posses kinetic energy{ability of particles to be in continuous motion} and kinetic energy increases with an increase in temperature.
When matter is heated the molecules in it move faster.
The state of matter with particles that move very rapidly is the gaseous state. In gases, particles are far apart and move freely, colliding with each other and the walls of their container at high speeds.
two states of matter that move freely are the liquids and plasma
Particles in matter move back and forth due to thermal energy, which causes them to vibrate. This vibration is a result of the kinetic energy of the particles constantly changing direction.
There is no phase of matter that has particles that do not move UNLESS the material is a SOLID at a temperature of ABSOLUTE ZERO.
faster. and matter then would move slower
faster
They move faster.
plasma
When matter is heated the molecules in it move faster.
When thermal energy is taken away from matter particles move more slowly. When thermal energy is added to matter particles move faster.
solid
Solid.
plasma
The state of matter with particles that move very rapidly is the gaseous state. In gases, particles are far apart and move freely, colliding with each other and the walls of their container at high speeds.
