A25.5 −g aluminum block is warmed to 65.9 ∘c and plunged into an insulated beaker containing 55.2 g water initially at 22.1 ∘c. the aluminum and the water are allowed to come to thermal equilibrium.

hi!

the answer would be solid.

explanation:

there are three essential states of matter:

in a solid, the particles are seen to be in a strict orderly arrangement, and only show restricted movement about their place.

in a liquid, the particles do not have a particular arrangement, and have a more free movement with respect to solid, and can change their position through the sample.

in a gas, the particles are most widely spaced, and have no defined arrangement. they have the most free movement of the other two states.

see the attached picture for a clearer idea.

hope this !

electron transfers between energy levels.

an atom contains an infinite number of energy levels. an electron can exist within any one of them, but not in between. electron can move from one level to another. however, those levels differ in energy. energy has to conserve.
