Because when a substance gets hot the molecules spread apart allowing more room for other substances to be mixed in to the solution. for example if you mix water (H20) with table salt (NaCl) it will fall to the bottom of the liquid unless agitated (stirred) or heated because both of these actions cause molecules to move and spread.

∙ 9y agoThe kinetic energy of solvent molecules increases with increasing temperature. As they have greater kinetic energy, they have a greater ability to overcome the forces that hold the solute molecules/ions together. Therefore, they are more easily able to form a solution.

∙ 14y agoDissolvation of most of ionic solids(salts) is an endothermic process.Therefore it absorbs heat energy from the outside and thus when we supply extra heat energy the efficiency of the dissolvation process arises and the solid dissolves easily.

∙ 11y agoAs the temperature of a solid increases, the atoms and/or molecules that make up the solid become progressively more excited due to the energy added. This increase in excitation increases the movement of the atoms/molecules, creating greater and greater space between the atoms/molecules as the solid as it is on its way to a phase change from solid to liquid to gas, depending on how much the temperature is increased.

Why is temperature usually stated when solubility's and densities are given?
Solubility and density are both temperature dependent. As temperature increases, kinetic energy increases and thus things become more soluble in solvents. Density decreases with increased temperature due to greater expansion.
Why does the solubility of water decreases as temperature increases?
because increase in molecular werght increases the hydrophobic part and decreasesv the hydrophilic part which is soluble. therefore increase in insuluble part decreases the solubility.
Why the solubility of calcium chromate decreases with increase in temperature?
due to the presencec of chromium metal as temprature increase solubility decrease
Why is solid silver more dense than liquid silver?
When a solid is melted it keeps its mass. It's the VOLUME that is slightly different. The density of most solids decreases slightly as temperature increases because solids expand when heated. As the temperature of the Solid Silver increases the volume increases slightly, even before the silver melts. This is due to the increased vibration of the silver atoms.I LIKE EGGS!!! XD
In which state do ionic compounds usually exist at room temperature?
due to strong electrostatic forces ionic compounds usually exist as solids at room temperature.
What will the solubilty of most liquids do as temperature increases?
The solubility increases as the temperature increases. This is due to the fact that there is more energy available the higher the heat.

How does increase in temperature affect the solubility of a gas?
When you increase the temperature the solubility of a solute in a solution increases. This is due to the fact that heat is required to break the bonds that are holding the molecules in the solid together. Note that the opposite is true for gases, though.
What is the relationship between solubility of solids and temperature?
For the solubility of solids in liquids and liquids in liquids, mainly,when the temperature increases, the solubililty increases. But in some compounds the solubility decreases with the temperature, such as NH3 and SO2 In the solution of gases in liquids,increase in temperature results to decrease in the solubility of gases.This is the reason why bubbles appear when tap water is heated.Increase in temperature allows the gas molecules to escape from the water molecules in the form of bubbles.The same explanation is applied to softdrinks which form bubbles as they warm up. These bubbles that you are seeing is like when you stir in too much koolaid powder into a glass of water, and soem settles to the bottom. When the water is heated, the amount of solute that can be dissolved in the liquid decreases, thus it does not have enough room to keep all of the CO2 gas in the liquid. The CO2 gas escapes into the air and is not noticable to the human eye.
How does carbon dioxide affect ocean water?
Temperature changes affect the solubility of CO2. Carbon dioxide is more soluble in ocean water due to the ocean temperature being low.
Why does the solubility of water decreases as temperature increases?
because increase in molecular werght increases the hydrophobic part and decreasesv the hydrophilic part which is soluble. therefore increase in insuluble part decreases the solubility.

What is the effect of temperature on the solubility of solids in liquid?
When we start heating an object, whether solid, liquid or gas, it's molecules start vibrating faster about a fixed point. They gather enough kinetic energy (due to the heat) to break free from their original state and start evaporating (in case of liquids). Since the molecules start vibrating faster, more intermolecular space occurs in between the molecules of the object. Thus, the solubility of the liquid INCREASES.
Why are solids solid?
solids have definite volume and shape. They are solids due to many factors including chemical compositions, the temperature in which they can stay solid, etc.
In which layer does temperature decrease as altitude increases?
Temperature will decrease as the altitude increases at all levels due to the thinning of atmospheric gasses.
