It would depend on the temperature of the water, or average kinetic energy. (KE) However, what you may be looking for is how much heat is needed to raise the KE, or temperature, of water. 4.184 kilojoules per gram is the heat required to raise the temperature of water 1 degree Celsius.
Salt water holds more heat than fresh water
No.
I don't know how much salinity is in fresh water.
3% of the earths water, is fresh water
The sun heats both fresh water and salt water through a process called solar radiation. However, salt water has a higher heat capacity and can hold more heat than fresh water. This means that salt water will heat up more slowly than fresh water, but it will also retain heat for a longer period of time. In general, both types of water will eventually reach the same temperature when exposed to the same amount of sunlight.
3% is fresh, but 1% is for drinking.
yes
The source of heat is the Sun.
The Pacific Ocean is salty, there is no fresh water in it.
The sun
fresh water doesnt have saltinity in it but, ocean water does.
The specific heat of both are essentially the same. i.e. it doesn't.
