The temperature of true water is in a beaker is 25 c after adding a piece of magnesium to the water the temperature increase is this an exothermic or an endo thermetic?
exothermic ? because energy released
Steps to see if adding salt to water change the temperature at which it boils?
To test if adding salt to water increases the boiling point of the water, do the following: boil a sample of pure water until it boils. Measure the temperature at which the pure water boils. Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle caused by an increase in temperature.
How will you increase solubility?
By stirring, heating, or adding more water :)
Does the volume of salty water increase when its temperature increases?
Yes, though it is slight, the volume increase is measurable when the temperature of salt water increases.
Why does temperature of water lowers on adding glucose?
It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.
What would increase the salinity of sea water?
Decreasing the temperature, evaporating water, or adding more salt.
An increase in a body of water's temperature caused by adding warmer water is called?
Thermal Pollution.

Does the volume of water affect the temperature increase when reacted with calcium oxide?
yeah the temperature does increase, when you increase the volume of water the temperature of calcium hydroxide increases too!
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle caused by an increase in temperature.
How do you increase your pH?
By adding potash or bicab to the water.
When developing film the temperature of the chemicals and water?
Meh.
Why doesnt water with ice get warmer till the ice is melted?
Any excess temperature (if the temperature is above approximately 0 degrees Celsius) will quickly be absorbed by the ice; this maintains the temperature at approximately zero degrees.Note what happens to the energy. When adding heat energy to water only, the water gets warmer - its temperature increases. When adding heat energy to a mix of ice with water, the energy will be used to change the state of the water, from solid to liquid. In other words, the water's potential energy will increase.
Does solubility of a substance in a solvent usually increases with an increase in temperature?
Solubility increases by adding more solvent. That is, the substance that the other is being dissolved into. For example, if mixing sugar and water, you would add more water to increase solubility.
How will you increase solubility?
By stirring, heating, or adding more water :)
