When we press the sponge, the air in the spaces is expelled out from the sponge. … The state of the sponge changes from the filled with the air to the no air form.
also What will happen if you will press the sponge? The sponge is actually made up of a mixture of solid and gas. When you squeeze it, the solid part changes it shape, but stays the same size. The gas in the holes gets smaller, so the entire sponge takes up less space. … Look at other objects that are compressible, but seem to be solid.
Who created sponges? The german scientist Otto Bayer is the inventor of polyurethane foam, which is what kitchen sponges are made out of.
in the same way Are sponges solid or hollow? Many sponges have solid architectures, in which a series of channels coalesce to expel water through one or more oscula and the large central spongocoel is essentially absent.

Why Sponge can be compressed easily?
Hint: The sponge is compressible being a solid because of the presence of air cavities inside the sponge. The sponge has numerous pores in it which can be referred to as air cavities, in which air is trapped and on compressing the sponge it comes out.
What happens when you squeeze a sponge underwater? When you look at a sponge, you will find that it a numerous pores which trap air in between them. So, when you squeeze a sponge under water, the air trapped inside gets displaced by the force you apply and water goes inside it. The air comes out in the form of bubbles and that is what you exactly see.
Can you squish a liquid? The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible. … You probably have experienced compressing something as hard as steel.
Are bath sponges alive? The natural sponges we use in our baths are actually animal skeletons. Bath sponges consist of a highly porous network of fibres made from a collagen protein called spongin. The skeletons are obtained by cutting the growing sponges and soaking the cut portions in water until the flesh rots away.
Why is SpongeBob a sponge?
The series’ creator, Stephen Hillenburg, was a marine science teacher and thought that the sponge was a fascinating and underrepresented animal. In The Origin of SpongeBob SquarePants, Hillenburg explained that he chose to focus on a sea sponge because he considered it “the weirdest animal” on Earth.
Do sponges have brains? Sponges are among the most primitive of all animals. They are immobile, and live by filtering detritus from the water. They have no brains or, for that matter, any neurons, organs or even tissues.
Do sponges feel pain?
Not much is known about the communication system of sponges as they lack a fully developed nervous system. That is also the reason for the sea sponges having the inability to feel pain.
Do sponges breathe? Sponges are animals that belong to the phylum Porifera, which means “pore-bearing.” Sponges breathe by moving water through pores, called ostia, which cover their body. Sponges respire through a process called diffusion.
How do sponges remove waste?
Sponges have small pores in the body walls through which water is drawn, and larger openings (usually near the top of the sponge) for exhalent currents. … Sponges use the water current and the process of diffusion to absorb oxygen from the water and to get rid of their metabolic waste products.
Why are sponges not solid?
Answer Expert Verified
sponge is compressible because it is having minute pores in which air is trapped . on presssing the air is expelled. it is still considered as a solid because it has a definite volume and shape does not changes unlesss compressed.
Why is it difficult to compress a liquid? Liquids and solids are hard to compress because, in liquids, the molecules are tightly packed when compared to gases. In solids, the molecules are very tightly packed. Therefore, they are hard to compress.
How can we compress sponge? Answer: A sponge has many minute holes which are occupied by air. When we press a sponge, air from the holes is expelled out and we are able to compress it. Infact, sponge is compressible due to the presence of air in the minute holes.
Why can’t you squeeze a sealed plastic syringe full of water?
you can’t squeeze a sealed plastic syringe that is completely full of water. Water has less compressibility. When you squeeze it, it has no place to escape. You can compress it very slightly.
What will happen if you squeeze the cotton balls with water? Packing cotton balls in water
They are incredibly light because most of their volume is just empty space filled with air. … When you drop a cotton ball into water, the water quickly creeps into all those tiny spaces between and inside the hollow cotton fibres.
What happens when you squeeze a bond paper?
A squeeze or squeeze paper is a reverse copy of an inscription, made by applying moist filter paper and pushing into the indentations by percussive use of a stiff brush. The paper is allowed to dry and then removed. The image is reversed from the inscription, and protrudes from the squeeze paper.
What is the hardest form of ice? 1 Answer
- Diamond. Its hardness is legendary. …
- Methane. At least it might be harder than nitrogen.
How cold can running water get?
Scientists have done experiments showing liquid water can exist at least down to minus 41 C (minus 42 F).
What happens if you squash water? Pressure and temperature can affect compressibility
But, squeeze hard enough and water will compress—shrink in size and become more dense … but not by very much.
