IGCSE Grade 10 Science Forces and distances between the molecules
|
Thermal energy is the energy arising from motion of atoms or molecules. It is the measure of average kinetic energy of the particles and responsible for movement of particles. Intermolecular forces tend to keep the molecules close to each other.
particle motion
The internal energy of atoms.
Motion of gas particles
mottion of surface particles
particles of matter
Electrically symmetrical atoms and non polar molecules having zero dipole movement due to their electron distribution may sometimes develop a momentary dipole also known as Dispersion force.
Pressure and volume remain same
Gases have the weakest intermolecular force present between molecules.
Different liquids are made of different molecules with different attractions for one another. If they are heated the molecules will increase their speed but the amount that they separate from each other and move up the tube will be different.
