Explanation:
volume=3x4x6=72cm³
density=mass/volume
so:
184.32/72=<u>2</u><u>.</u><u>5</u><u>6</u><u>g</u><u>/</u><u>cm³</u><u> </u><u>for</u><u> </u><u>the</u><u> </u><u>block</u>
Ionic compound is the answer
Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.

The answer to your question below
Explanation:
Processes from solid to liquid or from liquid to gas absorb energy.
Processes from gas to liquid or liquid to solid release energy.
Condensation phase change that releases heat
Freezing phase change that releases heat
Melting phase change that absorbs heat
Sublimation phase change that absorbs heat
Vaporization phase change that absorbs heat
