If you drop a marble into a glass of water the marble will sink because its?
Because the marble has a higher density than the water does
1 million drops of water equals?
Well, isn't that a happy little question! Imagine each drop of water as a tiny friend, coming together to create something truly special. When you have 1 million drops of water, you have a beautiful ocean of possibilities just waiting to be explored. Just like each drop is unique and important, together they create a masterpiece of nature.
How will knowing the density of a substance help you determine whether an object made from that material will float in water?
If an object is to float in water it must displace a volume of water equal to its weight; knowing the density of the substance that makes up the object allow a calculation to be made of the volume of water that must be displaced so that the object will float. If a substance has a density greater than that of water, it can be made to float by, for example, making it hollow; for example a ship made out of steel can be made to float as it has lots of hollow space inside it which means its effective density is less than that of water. Should the hull be compromised in any way, or by "splashing" over the top, the effective density can increase to the point where it is greater than that of water and the ship will sink. The density of water is not constant as it depends upon its temperature and things (like salt) dissolved in it; it was this change in density that led to loss of shipping and cargo which prompted the invention of the Plimsoll Line which is marked on the side of ships - it shows where the surface of water will be in different types of sea [water] for a given loading (the Line itself marks the maximum safe load). However, for small solid objects made of a substance of a greater density than that of water can still be made to float by using the surface tension of water: a clean sewing needle can be made to float if dropped very gently onto some water* as the force provided by the surface tension is enough to prevent the needle from passing through. If the surface tension is disrupted, for example by agitating the water, or by a drop of washing up liquid, the needle will sink. * If you don't have a steady enough hand: laying the needle on a piece of blotting paper or tissue paper and gently putting the paper on the water will make this easier to achieve - the paper will fairly quickly soak up water and sink away leaving the needle floating on the surface [tension].
Weight of 20 liters of water?
Oh, dude, let me drop some knowledge on you. So, 1 liter of water weighs about 1 kilogram, right? So, like, 20 liters of water would weigh around 20 kilograms. Easy peasy, right? Just grab a scale and you're good to go.
What is the volume of 100 milliliters of water?
Oh, isn't that just a happy little question! You see, the volume of 100 milliliters of water is the same as 100 cubic centimeters. It's like a little pool of tranquility, just waiting to bring life to your painting. Just remember, every drop counts and adds to the beauty of your creation.
What happens to water when it is heated up to 100 degrees?
The water becomes 100 degrees and is warm to the touch.
How can you find the density of a ball in water in a tube?
Density is a measure of the mass versus volume of an object. The density of water is 1. That is, 1 liter of water has a mass of one kilogram (it has a weight of 9.81 newtons). Thus, by measuring the displacement of the object in the water, you can find the volume of the object. Then by determining its mass with a balanced scale, you can plug the results into the formula: M/V = D. This will give you the density in kg per liter.
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
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.
How could you tell if a liquid has a higher or lower density than water?
If a liquid does not mix with water and you pour a little water on the liquid, then if the water sinks, the water has a higher density than the liquid; otherwise, the liquid has a higher density. If a drop of the water dissolves in the liquid, then you weigh an equal volume of both liquids. The heavier one has the higher density.
What is the mass of 1 water drop?
This depends on the volume of this drop.
How could you find the density of a potato?
first, you weigh it to get its mass. then you acquire its volume, since it has an irregular shape, you apply water displacement method. get a calibrated cylinder, note the initial water level and gently drop the potato in. measure the resulting water level and subtract it with the initial water level. this is your volume. density= mass/volume simply divide what you measured in grams with the volume of the potato (cm3). unit of density is grams per cubic centimeter or g/cm3
What is the volume of a drop of liquid?
1/15th of one millilitre.
Is liquid water denser than ice?
Yes. Because it has been observed that, when same mass of water is converted into ice, the volume increases up to nearly 1/11 th of that of the water. As density=mass/volume, so density is inversely proportional to volume. Simple experimental demonstration: -- Drop ice in water. -- Ice floats in the water. -- Ice must be less dense than the water, else it would sink. QED
What has greater density - 1 kilogram of water or 10 kilogram of water?
The density of a substance doesn't depend on how much of it you have. As long as the sample is pure, without any other stuff mixed in with it, the density of a drop of it is the same as the density of a supertanker full of it.
How would you find the density of plasticine?
Roll the plasticine into a sphere and measure the diameter and use the formula for the volume of a sphere V=pi r^2, then weight the sphere to get the mass and use Density = Volume upon Mass. Alternatively, use Archimedes' principle: 1) Weigh a piece of plasticine to get its mass. Very carefully fill a glass with water so full that it cannot contain one more drop of water. Immerse the plasticine in the glass, collecting the water that has run out of the full glass. The volume of the water is equal to the volume of the plasticine. Determine the volume of the water by either weighing it (density of pure water is 1 g per mL) or by accurately measuring the volume. Density = mass (g)/ volume (mL) 2) If you have a balance that can determine mass of an hanging object, first weigh your plasticine to determine its mass. Then attach it to string and take its mass hanging (the string also has mass). Then take its mass while the plasticine is just submersed in water. It will weigh less when submersed in water. The loss of mass when submersed is equal to the mass of water that has the same volume as the plasticine. (density of water is 1 g per mL) Now you can determine the volume of the plasticine since the mass lost in g equals the volume of water in mL. Density is the original mass divided by the volume.
Is the density of liquid water 1 grams per millaliter?
Not always. The density of water is 1 gram/mL at around 4 degrees Celsius. As temperature rises, kinetic effects kick in causing the volume per unit mass of water to increase, thus decreasing the density of water. Interestingly enough, the density of ice (frozen water) is also less than liquid water. The formation of ordered crystal lattices occupying relatively large amounts of space causes the rise in volume and an overall drop in density.
