If you drop an object in a cup of oil and a cup of water in which cup is the object more likely to float?
In the water. If you put oil and water in a container together, the oil will float on top of the water. This shows that the water is more dense than the oil. An object floats when it is less dense than the liquid by displacing the liquid. Water has a density of about 1 gram per cubic centimeter. Cooking oil has a density of about 0.92 grams per cc. So if you were to drop an object with a density of, say, 0.95 g/cc into the oil, it would sink. The same object would float in water.
What else can I help you with?
What will happen if we drop a piece of chalk and sponge in to a glass of water?
The chalk will sink, while the sponge will float. The chalk is denser than water, causing it to sink, while the sponge is less dense than water, allowing it to float.
What liquid does gold float on?
Gold can float on water if there's a layer of oil on the surface. To break the surface tension, a drop of Dawn soap will do the trick.
When you put a paperclip on water and then put one drop of soap why does it sink?
When you place a paperclip on water, the surface tension of the water keeps the paperclip from sinking. However, when you add a drop of soap, it disrupts the surface tension of the water, causing the paperclip to sink as the water is no longer able to hold it up.
How can you separate sand and styrofoam?
That will depend on the size of the styrofoam pieces. If they are significantly larger than the sand, you merely pick them out by hand. If not, then a sieve can be used assuming the sand will go thru the sieve and the styrofoam will be too large to pass through. You need to find a sieve with the right size holes. Another way is to add acetone and the styrofoam will dissolve, and the sand will stay behind, but this technique doesn't give you the styrofoam back again.
What happens when a drop of oil is stirred into a glass of water?
The oil will initially float on the surface of the water due to differences in density. Over time, the oil droplet may break into smaller droplets due to agitation, eventually dispersing throughout the water. However, oil and water do not mix because they are immiscible, so the oil droplets will not dissolve in the water.
How can you figure out whether an object will sink or float in water?
Drop it in water and see what it does.
What makes objects float on water?
If an object is less dense than water, it floats. I don't know exactly why having less density than something else makes something float, but I believe it has to do with the weight of the particles. The lightest ones rise to the top, while the heaviest ones drop to the bottom. This can be seen when you add oil to water.
Why do small drops of water float in air?
A small object has a larger surface area (in proportion to its weight) than a larger one. Therefore, a small object, like a small drop of water, will fall slower - it has more air resistance (again, in proportion to its weight). However, it will not float indefinitely; it will simply take longer to get to the ground.
What is it called when water rises after you drop an object in it?
When water rises after you drop an object in it, it is called displacement. The water is displaced by the volume of the object that is submerged, causing the water level to rise.
What happens when you drop anything in water?
When you drop most things in water the object sinks and the water rises.
Do blocks float?
Depends on what they're dropped into. Water - no. But drop them into something that's denser than aluminium and they will float.
Do aluminum blocks float?
Depends on what they're dropped into. Water - no. But drop them into something that's denser than aluminium and they will float.
Does volume alone determine weather an object will float or sink?
No. A very big rock has a great deal of volume- but it also has a great deal of weight. Drop it in water, and it will sink like a........rock. It is the weight per measure of volume that determines density. If the density is less than the liquid, it floats. Greater than the density of the liquid, it sinks.
Does the paper drop float or bounce?
A paper drop typically floats due to its lightweight properties. It is less likely to bounce because of its thin and fragile structure.
How do you calculate the volume of a irergular object?
Use a measured water cylinder, drop in the object, the amount of water displaced represents the volume of the object
Do eggs float or sink when they are boiled?
unboiled eggs float, but the boiled ones sink.
How do you expect the water level to change when the apparatus is placed in warm water?
When the apparatus is placed in warm water, the water level in the apparatus is expected to decrease as the liquid inside the apparatus expands due to the increase in temperature. This expansion will cause some liquid to spill out and the water level to drop.
