I don't know ow you add energy to the sea but if you could then the tides or waves would rise much higher that may cause Tsunami.
It will either get hotter or evaporate, or perhaps a bit of both.
Adding energy to a glass of water typically increases the temperature, causing the water molecules to move faster. Removing energy from the water would cause it to cool down, slowing down the movement of water molecules.
When you add kinetic energy to a solid the molecules won't move
what answer
get off the couch occasionally...
and add it to water
this emans to water it down, or add water...
That happens when there is a phase transition; for example, when ice melts, it takes energy to convert ice at zero degrees, to water at zero degrees.
The water will be displaced, and the water level will rise.
Nothing
crystals form
it turns brown?
