What else can I help you with?
Why can a sponge return to its original shape after it is being compressed without referring to to its material being flexible?
A sponge can return to its original shape after being compressed because of the air pockets present within its structure. When pressure is applied, these air pockets collapse temporarily, but once the pressure is released, the air flows back into these pockets, causing the sponge to expand back to its original shape.
Why do sponges absorb water?
There are millions of tiny pockets in the sponge that air empty; those pockets act as a greenhouse, letting heat in, but not letting heat out, except for a sponge, it's water. Those pockets get filled with water.
How does absorbent happen?
The fluid goes inside the air holes/pockets in the soil/sponge/material.
Is a sponge a good insulation?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
Why sponge is compressible?
Sponges are compressible because they are porous and made up of interconnected air pockets. When pressure is applied to a sponge, the air within the pores is forced out, allowing the sponge to compress.
Sponge is a solid yet you ca compress it why?
You can only compress it to its existing volume (which you can't change without changing the density). The key is that a sponge isn't completely solid, it has pockets of air throughout it. Thus, you can compress those pockets of air and never change the volume of the actual solid.
Why does a sponge have less mass than a book of the same size?
A sponge has less mass than a book of the same size because a sponge is less dense. The sponge is made up of more air pockets and less material compared to the dense paper and binding of a book, which results in the sponge weighing less for the same size.
Why does sponge float but rubber blocks sinks?
Sponge is porous and filled with air, which makes it less dense than water, so it floats. Rubber is denser than water and does not have air pockets, causing it to sink.
Why is a sponge a bad conductor off heat?
A sponge is a bad conductor of heat because it is made up of mostly air pockets trapped in its porous structure. Air is a poor conductor of heat compared to solid materials, which prevents heat from transferring efficiently through the sponge.
What is the density of a sponge?
The density of a sponge can vary depending on its composition and structure, but it is generally very low due to the many air pockets present within the porous material. This low density allows sponges to float on water.
Why does your sponge sink in the middle?
A sponge sinks in the middle primarily due to its structure and the distribution of air pockets within it. As the sponge absorbs water, the denser water fills the pores, causing it to become heavier and less buoyant. Additionally, if the sponge is not uniformly saturated, the uneven weight distribution can lead to it sinking in certain areas, particularly the middle.
How does that substance inside the bone look?
An outer layer of Cortical Bone surrounds a spongy bone centre. The pockets within the sponge are filled with Bone Marrow. The inner bone looks like thick sponge filled with slime
