How can the volume of a irregularly shaped rock be measured?
One way would be to get a container into which you could put the rock completely, fill it to the brim with water (without the rock in it), then put the rock in and measure the volume of the water that flowed out.
How could you use a fish tank to find of volume of an irregularly shaped object?
Using a graduated beaker, add water sufficent to totally immerse the object. Note the initial volume of the water without the object.
Why do you need to use the water displacement method for some objects and not others?
The water displacement method is used to find the volume of irregularly shaped objects. This method is not necessary for regularly shaped objects whose volume can be easily calculated using geometric formulas. Irregularly shaped objects do not have a straightforward formula for volume calculation, hence the need for the water displacement method.
How do you find volume when mass and density are not givin?
It depends on the way the question is asked. If you are dealing with a cubic or rectangular object, you measure the length, width, and height, and multiply them. If it is a spherical or irregularly shaped object, you could used water displacement to find its volume. If it's a liquid, you could use a graduated cylinder to measure its volume.
A scientist immerses an irregularly shaped object into a beaker of water and notes how far the water rises.What property of the object is the scientist measuring?
The amount the water rises is dependent of the volume of water displaced by the object - thus it can be used to measure the volume of the immersed object. If the object did not immerse completely - if it floated - the displaced fluid could instead be used to calculate the relative density of the object - when combined with the total volume.
Could the water displacement method be used to determine the volume of a rectangular object as well as an irregularly shaped object?
Yes. It doesnt have to be a irregular even though sometimes it is easier just to do the math... for a rectangular object. l x w x h= volume
What will be used to determine th volume of irregularly shaped solids?
To determine the volume of irregularly shaped solids, you can use the method of water displacement. Fill a container with water, then submerge the irregular solid in the water and measure the change in water level. The volume of the solid is equal to the volume of water displaced.
Could the water displacement method be used to determine the volume of a regular shaped object as well as an irregular shaped object?
Yes
How the volume of a heavy irregularly shaped object may be determined experimentally are there any limitations?
The volume of a heavy irregularly shaped object can be determined experimentally using water displacement method - submerging the object in a known volume of water and measuring the increase in water level. Limitations may include buoyancy effects, difficulty in accurately measuring small volume changes, and water absorption by porous objects.
Why do you need to use water displacement method for some objects and not for others?
Because some objects have an irregular shape, therefore cannot be measured like a square could.
What would happen if red blood cell is large?
Irregularly shaped blood cells can cause problems with clotting and proper blood flow. Think of the sickle cell disease. Although you're asking about irregularly sized and not irregularly shaped blood cells, I would assume that similar problems would occur. If the blood cells were too large to allow proper and free movement I should think that clotting and the risks/pains associated with abnormal blood clotting could occur. It really depends on how large we're talking.
What apparatus would you use to measure the size of a rock?
A ruler or a measuring tape could be used to measure the dimensions (length, width, height) of a rock, while a scale can determine its weight. For irregularly shaped rocks, a water displacement method can be used to calculate volume, which can then be used to estimate density or mass.
