What else can I help you with?
How does salt affer floating?
Adding salt to water the density is increased.
How does salt make water heavier?
Salt dissolves in water, adding more mass to the water without significantly increasing the volume. This increased mass due to the dissolved salt makes the water denser, causing it to be heavier than plain water.
Why does salt water take longer to boil?
The boiling point is increased after adding impurities to water.
How does adding salt to water affect its volume?
The salt-water mixture will have the same weight as the sum of the weights of the water and the salt. The water, itself, doesn't gain weight in a strict sense, but the salt-water mixture will be heavier than the plain water. Salt water is denser than fresh water.Yes, the weight of any salts dissolved in water will be additive with the water.weight of salt + weight of water = weight of salt and water in solution
How can the conductivity of water be increased by adding a substance?
Adding a substance like salt or minerals to water can increase its conductivity by providing more ions that can carry electrical charge.
If you put 4 milliliters of salt into 50 milliliters of water why does the volume not increase by the amount you put in?
It's because the salt disolves into the water instead of adding more volume to it. The salt molecules are "taken apart" (dissociated) by the water molecules, and they are converted into Na+ and Cl- ions. These ions can fit "between" the water molecules, and can do so without increasing the volume of the solution. More salt can be added without increasing the volume, too. That is until saturation is reached, and then no more salt will go into solution. Adding additional salt beyond this point will increase the volume.
What is the rationale for reducing dietary salt for patients with high blood pressure?
Salt which is taken in by the body into the blood, causes the water in the body to follow salt into the blood vessels. This increased uptake of water into the circulatory system increases the volume of blood in the blood vessels. This increased volume increases blood pressure.
How can you make salt water denser?
Density is the mass per unit volume. Therefore, adding salt increases the mass of the water by a larger scale than it does the volume of the water. Actually when you add salt to the same volume of water the mas of the water has a noticeable increase, where as the volume appears to the same ( the volume does increase; however the change is so small that it is unnoticeable ,thus we say it stays the same). So a larger mass divided by the same volume gives you an increase in density.
How does salt water effect floating?
The salt water has a greater density and the floating is easier.
Why is salt water so dense?
Salt water is denser than fresh water because salt increases the mass of the water by adding more particles to it, which makes the water heavier and more tightly packed. This increased density allows objects to float more easily in salt water compared to fresh water.
What is the independent variable in this experiment does adding salt to water lower its freezing point?
salt. added by new author: As the amount of salt in the water iw increased the freezing point of water is decreased i.e. lowered. This is a negative correlation.
Why does salt water help you float?
Floating is the another name for the force called buoyancy and buoyancy is reliant on the density of the floater and the liquid the floater is floating in. The less dense the floater is, the more buoyant the floater will be. Salt, when added to water, makes the water more dense than the water by itself. This can be seen in an obvious way by filling a glass of water to the top and adding salt to it. It won't overflow as long as the salt is added in a form that dissolves rapidly. The volume doesn't increase, but the salt's mass is now added to the water's mass resulting in more mass for a similar volume. the formula for density is mass/volume. But that's not the whole story. The volume of water actually decreases when salt is added, so the effect on the density of the water is increased. Salt is an electrolyte. When dissolved the sodium and chlorine ions freely associate with the water. The presence of the ions causes an effect called electrostiction, which results in the water's molecular structure changing to a more compact form (bending if you will), which causes the volume to decrease. Since the density (mass/volume) of the human body (being over 60% water) is very close to the density of water, people may or may not float in water. Adding salt to the water increases the density of the water, not only through the added mass, but also by pulling the water molecules closer together. The increased density of the salt water will result in the increased buoyancy of the floater.
