The further down you go, the colder it gets. This is due to a lack of sunlight as depth increases.
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
solubility generally increases with a temperature increase
Yes, calcium chloride increases the temperature of water.
With a rise of temperature, the solubility increases
Although the solubility of most substances increases with temperature (eg you can dissolve more sugar in water when it is hot than you can in the same amount of water when it is cold) with gases the solubility decreases with temperature, so that cold water will hold more gas than the same amount of hot water. As oxygen is a gas its solubility decreases as the water temperature increases.
The shallower the water is, the warmer it can be. Direct sunlight will warm the water and as the water deepens, the warmth from the sun cannot reach as far. This creates a slightly colder temperature.
Not directly you cant, but sea temperature does decrease with depth, although its not a straight line graph ( though depth : pressure is.)
The sun can't reach the thermocline layer to heat that depth of water
The water molecules spread out as temperature increases, which allows the alum to dissolve more readily. Conversely, as temperature decreases, the water molecules become more compact which causes the alum to be less soluble.
The sun can't reach the thermocline layer to heat that depth of water
In general, the answer is the water gets colder as you go deeper. But, there are exceptions. For example, at the Galapagos Rift there are intensely hot (hundreds of degrees) springs at depths of almost two miles.
Water pressure increases as depth increases.
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
decrease because when temperature is low water is present in atmosphere which let sound to go fast
­The decrease in vegetation increases the amount of light that hits the water, which increases the temperature of the water ­Deforestation also increases erosion ­Erosion makes the water muddy, which increases the light absorbed
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Yes, pressure does increase as your depth increases in the water
