Ella makes this table to organize her notes on whether atoms gain or lose energy during the changes of state. A 2-column table with 2 rows. The first row has entries Gain Energy, Lose Energy. The second row has entries nothing, nothing.

Which changes of state should she place in the column titled "Lose Energy"?

freezing, boiling, and melting
melting, vaporization, and sublimation
sublimation, deposition, and condensation
freezing, deposition, and condensation

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

What organization and environment is described above?
