400
why do you think temperature is the measure of the average energy of motion of all the particles within a substance.
What is particles move at different speeds
400
how is sublimation different than a vaporization, condensation, and melting.
What is sublimation does not include a liquid phase
500
a form of energy arising from the motion of all the particles in a system; heat energy moves between things that are at different temperatures; also called thermal energy
What is heat energy
500
the amount of a substance that will dissolve in a given amount of another substance
What is solubility
500
the measurement of the average energy of motion (heat energy) of the particles of matter in a substance
What is temperature

Arlen adds sugar to a glass of water. He stirs the water for three minutes. At the end of his stirring, he cannot get more of the sugar to dissolve. Suggest two ways Arlen could get the rest of the sugar to dissolve in the water.
What is Arlen can heat the water or add more water.
