Is floating in salt water an example of bernoulli's principle?
No. It's an example of Archimedes' principle.
A cork is floating in salty water As more salt is added to the water to increase its density the cork will?
it float at the same level in water.
Does the ship sink or rise in salt water?
The ship has two forces that affect the fraction of its volume that is above the surface of the water. The ship's weight is the downward force. The buoyant force is the upward force. Since the ship is floating, the magnitudes of these two forces are equal. The buoyant force is dependent on the density of the water. The density of salt water is greater than the density of fresh water. Let's look at the equation below. Buoyant force = Density * g * Volume of displaced water According to the equation, the buoyant force is directly proportional to the density. Since salt water is denser than fresh water, the buoyant force will be greater in salt water than fresh water. This force will push the ship up higher than if the ship was floating in fresh water. You could do this at home. Make a saturated solution of salt water. Then place a small wooden block into a glass of salt water. Use a ruler to measure the height of the fraction of the block that is above the surface of the salt water. Then place the block into a glass of fresh water and measure the height of the fraction of the block that is above the surface of the fresh water. You will see that the block is floating higher is salt water than in fresh water.
Why does salt in water make objects float?
Things float in water if they are less dense than the water they are floating in. Putting salt in the water makes it more dense, so things that are a little more dense than ordinary water float in salt water.
Why does sinking and floating happen?
It happens because if you put a certain amount of salt in a cup with water the more salt you put in the more things you put in will float.
What are the controls and variables for Seperating salt from water?
I dont know about the control but the independent variable is the amount of salt water and the dependent variable is the amount of water and salt rendered.
What are the independent and dependent variables of adding salt water to boiling water?
The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.
What are the dependent variable for this question Will water with salt evaporate faster than water without salt?
If you are trying to measure how fast an ice cube melts with or without salt added, your Independent variable would be amount of salt added, and your Dependent variable would be the amount of time it takes to melt.
Is crystal salt a dependent variable?
No.
When you conduct and experiment the condition you are investigation the one thing you want to know about is called?
The independent variable! =] the dependent variable is what is changed by the independent variable... Eg... And a bad one at that lol... But the affect of salt on the boiling point of water... Salt is independent variable... Dependent is the boiling point =]
What is the dependent variable for how does salt affect the freezing point of water?
The concentration of the salt solution, or salinity. It changes as shown in the related link below.
Who invented an egg floating in salt water?
woetso jigdak invented an egg floating in salt water.
What materials is required for salt water and plain water science project?
If it's for science fair you need a control group, experimental group, and independent variable/dependent variable. I'd suggest what is the effect of salt water on.... whatever it is you like! Materials include: graduated cylinder (measure water equally) water beakers whatever the salt water is testing
What affect does salt to freezing point hypothesis indipendent and dependent variable?
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
How does salt water effect floating?
The salt water has a greater density and the floating is easier.
What is the dependent variable in the project which melts faster ice with salt or with out salt?
It would be the amount of time it takes to melt.
What can affect an object floating?
Salt in the water
