What else can I help you with?
Did the properties of table salt and water change when they were stirred together?
Salt dissolves in water. The resultant liquid has higher density than pure H2O. Teh salt solution has less electrical resistance than pure water, it tastes different too. Depending on how much salt and how much water were mixed, some salt might remain undissolved (the mixture is saturated).
Do strong acids have higher concentrations than weak acids?
No. The concentration of and acid and the strength of an acid are two unrelated values. The strength of an acid is the degree to which it will break apart into ions when dissolved in water. It is an inherent property of any given acid. The concentration of an acid is how much of it is present in proportion to its solvent (usually water) and is independent of any properties of the acid itself. You can take a solution of some acid and add it to water to lower the concentration or boil off some water to raise the concentration, but the properties of the acid itself remain the same.
Does the temperature of the water effect a science experiment?
Yes. How much it affects the experiment depends on exactly what the experiment is and how much the temperature has changed, but any change in temperature affects water's physical and chemical properties.
If it has higher density does it also mean that it has higher resistance?
Not necessarily. Higher density refers to the amount of mass in a given volume, while resistance is the opposition to the flow of current in a material. They are not directly related, as resistance is dependent on factors like the material's composition, length, and cross-sectional area.
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.

What is the major advantage of air?
The concentration of oxygen in the air is much much higher than in the water. This make obtaining oxygen much easier and strenuous activity (to a level higher than that is water) possible.
Can a disaster be predicted?
Many disasters like hurricanes and thunder storms can be predicted. However, many disasters, like tornadoes and earthquakes, cannot be predicted with much accuracy.
What is the major advantage of air breathing?
The concentration of oxygen in the air is much much higher than in the water. This make obtaining oxygen much easier and strenuous activity (to a level higher than that is water) possible.
What is the difference between fresh water and ocean?
Ocean water has a higher salinity (salt content) than fresh water does.
What do the unusual properties of water mostly comes from?
Mostly from the fact that there is strong hydrogen bonding between the molecules. This, for instance, gives water much higher melting and boiling points than we'd otherwise expect for such small molecules.
Sodium oxide melting point higher or lower than water?
Much higher. Water melts around 1 0C. At this temperature and much higher, sodium oxide is a solid.
What two properties determine the density of sea water?
Temperature and Salinity. Both are important although temperature has a much greater effect than salinity on seawater density.
What is the density of water in the solid state compared to that in the gas state?
Much higher.
How much does water weigh with sodium chloride together?
This depends on the sodium chloride concentration; higher the concentration, higher the density.
Why does salt not evaporate with water?
Salt does not evaporate with water because it has a much higher boiling point than water. When water evaporates, it leaves behind the salt, which remains solid. Salt can be dissolved in water, but it does not evaporate along with the water molecules.
Why does a kilogram of lead occupy a much smaller volume than a kilogram of water?
lead has much higher density
