What is the difference between filter paper and a sieve?
filter paper is paper and a sieve is a kitchen utensil used to put objects (pasta,rice) and drain water.filter paper is used to seperate smaller granules (sand etc.) and a sieve is used to seperate larger granules(peas, rice, pasta etc.)
How can you separate sand and pebbles?
As long as the particles of sand and pebbles are of different size, you can separate them using a sieve (sifter). The smaller sand particles will pass through the sieve whereas the pebble molecules will not. This is the process that occurs in sifters sold as children's toys.
What cannot pass through an opaque material?
Light cannot pass through an opaque material.
Why is the cell membrane called semi-permeable?
The cell membrane is hydrophilic outside and hydrophobic from inside thanks to the phospholipid. The membrane also contains protein gated channels which allow some molecules to pass through and ion channels. The transport in an out of cells is also controlled by osmotic pressure, the electric charge etc.
What type of material always lets light pass through it?
Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.
Can a cork pass through a sieve?
No, a cork cannot pass through a sieve. The cork's size is typically larger than the openings in a sieve, preventing it from passing through.

Why do water get pass from sieve?
Water can pass through a sieve because the holes or mesh in the sieve are larger than the water molecules, allowing the water to flow through while trapping larger solid particles. The sieve acts as a filter, separating the water from any solid materials that are too big to pass through.
If you pour rock salt over a sieve will it go through?
No, rock salt, being larger in size than the holes in the sieve, will not go through the sieve. The sieve will only allow smaller particles or substances to pass through, while retaining larger ones.
How could you separate sugar and white rice?
To separate sugar and white rice, you can use a sieve or a fine mesh strainer to filter them based on their size differences. Since sugar granules are much finer than rice grains, this method allows the smaller sugar granules to pass through while retaining the larger rice grains.
How do you separate flour and iron?
Pour into a sieve or colander, the sand will pass through the open mesh, leaving the larger marbles trapped inside the sieve.
What happens when you put sand in the sieve?
When you put sand in a sieve, the smaller particles of sand will pass through the sieve mesh while the larger particles will be trapped on top of the sieve. This allows for the separation of the sand based on particle size.
What does sieve?
A sieve is something that separates insoluble substances from a solution. In the kitchen, a sieve is meshed wire, with tiny holes in it to allow the water to pass through, but doesn't allow insoluble substances.To sieve (verb) means to sift or separate things.
What piece of equipment is used to take pebbles out of soil?
A sieve or a sieve shaker is commonly used to separate pebbles from soil. The soil is poured onto the sieve, and the pebbles are physically separated by shaking the sieve to allow smaller particles to pass through.
What feature of salt and pasta allow them to separate with a sieve?
Salt and pasta can be separated using a sieve due to differences in their particle size and shape. Salt consists of small, uniform crystals that easily pass through the holes in a sieve, while pasta is larger and irregularly shaped, making it unable to pass through the sieve. This physical difference allows the smaller salt crystals to fall through the sieve while the larger pasta pieces remain on top, facilitating their separation.
How does a sieve or colander demonstrate the property of selective permeability?
A sieve or colander demonstrates selective permeability by allowing smaller particles, like water or liquid, to pass through while blocking larger particles, like solids. This property is based on the size of the holes or pores in the sieve or colander, which determine what can pass through and what gets caught.
What is sieve size?
It refers to the go / no go boundry, a 5 mm sieve wont let anything larger than 5 mm through, but anything less will pass through.
