A.) The particles will lose energy, come closer together, become more dense and sink.
B.) The particles will gain energy, spread apart, become less dense and keep floating.
C.) The particles will lose energy, will spread apart, become less dense and sink.
D.) The particles will gain energy, come closer together, become more dense and sink.
