How could you seperate a mixture of sand and small pebbles?
In geology and civil engineering sand and gravel have specific meanings! Sand is material that varies in diameter from 1⁄16 mm upto 2 mm. Any material larger than this is either gravel (>2 to 4 mm), a pebble (>4 to 64 mm), a cobble (>64 to 256), or a boulder (>256 mm). As the difference between gravel and sand is the size of the grains then a sieve with a mesh equal to the maximum diameter of sand could be used to sieve the material. All the material passing through the sieve would be sand (or smaller material) and anything trapped on the sieve would be gravel or larger material.
What physical property can be used to separate sand and sugar?
1. Add water to the mixture and stir to dissolve the sugar. 2. Filter out the mixture, the water with the sugar in it will pass through, the sand will not. 3. Then, evaporate the water using a Bunsen burner if you want to do it quicker to leave behind the sugar.
What are the applications of sieve analysis?
A sieve analysis test is a procedure to separate fine material from course material by means of a series of woven or perforated surfaces. The proportion of different size particles are recorded. This record is the conclusion of the analysis. Art Gatenby agatenby@cscscientific.com
How would you separate ground pepper and pebbles?
First put the mixture in a colander and separate the salt and pepper from the pebbles. Then put the salt and pepper in water and stir it to dissolve the salt. The pepper will not dissolve, and you can remove the pepper. Then allow the water to dissolve and you will be left with the salt.
What are three uses of filters to separate components of mixtures?
Filters are commonly used to separate solids from liquids, such as when making coffee. They can also be used to remove impurities from liquids, like in the water purification process. Additionally, filters are used to separate larger particles from smaller ones, as seen in the separation of sand from water.
How would you separate a bowl of marbles and iron fillings name 2 ways?
Use a magnet to attract and separate the iron fillings from the marbles, as iron is magnetic while marbles are not. Use a sieve to separate the marbles and iron fillings based on their size differences. The marbles will remain on top of the sieve while the smaller iron fillings will pass through the sieve holes.
Define amorphous solid?
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
How do you separate water and rice?
You can do this with a sieve. Simply pour the mixture into a sieve, the water will drain through the tiny holes, whereas the rice will stay in the sieve because it is too large to go through the tiny holes.

What is a sentence using the word sieve?
You can use a sieve to find all the primes numbers between 2 and any given number n.
How can you separate raisins and flour?
Use a sifter; the flour will fall through while the rice is caught by the screen.
What is the peculiarity of prime numbers in sundaram sieve?
The sieve of Sundaram sieves out the composite numbers just as sieve of Eratosthenes does, but even numbers are not considered; the work of "crossing out" the multiples of 2 is done by the final double-and-increment step.
How do you separate potassium nitrate from iron?
put them in 2 different spots
What is a solid shape with 3 surfaces?
A cylinder

What can you conclude if you have two unidentified solids of the same texture and color that have different solubilities in 100 grams of water at 20 degrees C?
If the two solids have the same texture and color but different solubilities in water, it suggests they are two different substances with distinct chemical properties. The varying solubilities indicate differences in their chemical structures and interactions with water molecules. Further analysis such as melting points, chemical reactions, or spectroscopic techniques may help identify the substances.
What impurities do you find in river water?
1. Suspended solids 2. Colloidal solids (nonsettleable solids) - Do not dissolve in water
