Salt Water, do to its small salt particles which not only the water holds the heat ,but the salt particles TOO!!!
Most brines for heat transfer systems are very heavily salted solutions to the point where there is more salt than water [by weight] in them.
Salt water holds more heat than fresh water
land
Soil absorbs heat much faster than water, but water does not have air in between like soil so it doesnt lose heat as fast, so water holds heat longer
yes
Land holds more heat than water because the earth has magma and lava but water doesn't
It doesn't make the solution hold heat longer but it increases the boiling point of the solution by decreasing the vapor pressure.
i think sand but you should testit first ot find out
salt water can hold heat the most but just a little ahead of water (Fresh). that's all i now for now, I'm orking on it for science!
the land
Salt water has a higher boiling temperature than fresh water so it would take longer than fresh water to heat up. this is because of the tendancy for H2O to 'cluster' around and cling to the salt molecules. This means that fresh water will evaporate faster than salt water (depending on the concentration).
No.
Land absorbs heat energy from the sun quickly, but it also releases the heat (cools down) more quickly than water. Water reflects more of the energy than land does, so it takes longer to warm. Water also holds the heat longer than land. This is why the sea is warmer for swimming at the very end of summer, even when the land is cooling.
