What is the affect of temperature on the solubility of calcium sulphate in water?
See http://www.fiu.edu/~pricer/Calcium%20Carbonate.pdf.The solubility of CaCO3 depends on the solubility of CO2. The solubility of gases decreases in water as the temperature rises. This behavior is discussed at http://antoine.frostburg.edu/chem/senese/101/solutions/faq/temperature-gas-solubility.shtml.
What happens to the solubility of solids such as KNO3 when temperature of the water rises?
KNO3 and NaClO3 have the same solubility at approximately 95 Celsius. NaClO3 can be more soluble than KNO3 at different temperatures, but it is not seen that KNO3 is more soluble than NaClO3.
Which piece of evidence would prove that a reaction is exothermic?
All you need is a thermometer. If the temperature rises as the reaction goes to completion, then the reaction is exothermic. If the temperature decreases, then it's endothermic.
What happens to relative humidity when temperature rises?
When temperature rises, the capacity of air to hold water vapor increases. Consequently, the relative humidity decreases because the amount of moisture present in the air remains the same, but it is spread out over a larger volume.
Why is it that when you go up a mountain you get colder because your near to the sun?
because air pressure decreases as altitude increases. As air rises, the pressure decreases. It is the lower pressure at higher altitude that causes temperature to be colder on the top of a mountain compared to sea level.
What effect does temperature have on the solubility of a solid solute in a liquid solvent?
solubility increase as the temperature rises rises thus its directly proportional under normal circumstances
What happens to viscosity as temperature increases?
As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.

What happens to the solubility of potassium nitrate as the temperature rises?
The solubility of potassium nitrate increase with the temperature.
How will the solubility of anhydrous sodium sulfate vary with temperature?
Sodium sulfate is unusual in that its solubility becomes largely independent of temp at 49.7 °C( meaning instead of increasing solubility as temp rises it forms a plateau and actually decreases slightly) See the Web Links to the left of this answer for a direct link to a graph of the solubility vs. temperature, as described above.
How is solubility related to temperature?
This relationship is most often observed when dealing with liquid solutions. The solubility of solids and liquids in a liquid solvent tends to improve as the solvent's temperature increases, while the solubility of gases in the same type of solvent generally decreases as its temperature rises.
What is the general relationship between solubility of a substance and temperature?
As the temperature increases the solubility also increases.
How does temperature affect surface tension?
As the temperature rises, surface tension decreases.
Does the solubility of potassium nitrate in water increase or decrease as the temperature rises?
Increase
What happens to radiation from an object as its temperature increases?
radiation from object decreases as the temperature rises
How does a fluid-filled thermometer works?
As the temperature of a fluid increases, its volume increases, and as the temperature decreases, its volume decreases. Since the liquid in a thermometer is in a closed container, the fluid rises when the temperature increases and lowers when the temperature decreases.
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
