what type of matter is this1

Apuntes

what type of matter is this? what is the definition of temperature? Summer, sun and a thermometer what is thermal expansion? what is thermal contraction? During Ms. Lee's demonstration, when the metal ball was over the fire, it: how do you draw that the particles have more kinetic energy? what is thermodynamics? when a balloon is cooled, kinetic energy in it Gas particles in a HEATED balloon what temperature scale do we normally use in this science class? what is diffusion? a substance that is being heated has less kinetic energy. greater mass = what is thermal conductivity? particles can stop moving completely. solids can expand. what type of matter do you think this is? (the particles are very spread out) what is freezing temperature? what is the relationship between temperature and particle motion? the faster the substance diffuses, the faster the particles are moving.
