How would you measure the mass of a drop of water?
use a measuring cup
Drop 10 coins of the same size and mass into a container filled with water, making sure that the water that overflows from the container is collected. Now measure the volume of the water overflow an multiply it with the density of water which is 1 kg/l. Now divide the total mass by 10 to get the mass of one coin.
You would measure the swimming pools length, width and depth to determine how many cubic feet of water is in the swimming pool. Length x Width x depth = cubic feet. Then measure the mass of 1 cubic foot of water by building a box 1'x1'x1'. Once you know the mass of 1 cubic foot of water - you'll know the mass of the water in the swimming pool.
How could you determine your mass using water a bathtubsomething to measure water with and Archimedes' princilpe?
It's quite difficult to directly measure mass. It's relatively easy to measure force, which is what a spring scale does. (A balance scale measures force also, but it measures the force exerted by a known mass compared to the force exerted by an unknown mass. This corrects for local variations in gravity.) Answer: Spring scales can measure mass by comparing the weight of an unknown amount of material to that of a known mass of…
How big is a drop? "A drop" is not a precise measurement. It depends on a number of factors. If you measure how big the drops of water are you're talking about, (in millilitre) then you could figure out the number of molecules based on the fact that Avogadro's number of water molecules have a volume of about 18 milliliters. Avogadro's number is 6.022 * 1023 (particles) per mole One drop: average volume about 0.05…
A metric cup is 250ml, and is a measure of volume, not mass. How heavy that will be depends on what you are measuring. If you are measuring something like water, the answer would be 4, because 1l of water has a mass of a kilogram. Searching the internet would tell you the mass of a cup of various substances.
If it is a substance that will not react with water, then you can measure its volume by placing it in a container of water and note the displacement of the water (how much the water level goes up in milliliters). You can measure the mass of the object on a scale (probably should do this before putting in the water), then density = mass/volume.
No. A litre is a volume, a mass is a mass. You could measure a litre in litres! and mass in grams or kilograms. It is only in the case of pure water, at a sepecific temperature (4 deg C) and specific pressure (760 mm of Mercury), that a litre of water has a mass of 1 kilogram. At any other temperature or pressure, the conversion is approximate. And that applies only to pure water…
I would recomend measuring a pumpkin based on its mass, which can be found by weighing it (not that weight= mass, but weight can be used to determine mass as long as the pumpkin remains on Earth) You could also determine the volume by measuring how much water it displaces. I would stick to mass, though
