Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
C. A bowl filled with apples is the more porous of the four. Porosity is a function of the size of the fruit. The larger the fruit, the more porous the bowl will be (the more air or water that can be placed in the bowl). The smaller the fruit, the less porous the bowl will be. Compare with a bowl of stones and a bowl of sand. The stones are more porous because the sand can be more densely compacted, leaving very little room for water.
If water droplets penetrate within 3 minutes or less it is considered porous, if water droplets remain on top it is considered non porous..

Oak is dense and considered a hardwood. That being said, it can absorb liquids, making it porous but, not as poroius as say plywood or mdf.
it would make a fart noise and die ha ha
The Gravel will absorb the water until it can absorb anymore.
Gravel does not actually hold water in the sense of absorbing or retaining moisture like a sponge. Instead, water flows through gravel easily due to its porous nature, making it a good material for drainage and preventing water buildup in soil.
you can wait until the water evaporates
Gravel is a small, rounded rock typically in varying shades of gray, brown, or tan. When mixed with water, gravel does not dissolve or react chemically, but it allows water to pass through easily due to its porous nature.
It would die. Frogs have a porous skin and the slat in the sea water would quickly kill it, because fogs are adapted to live in fresh water.
No, the gravel sinks when placed in water and is therfore more dense than water. This means that given two equivalent volumes one of water , one of gravel, the mass of the gravel will be greater than that of the water.
When gravel is mixed with water, the gravel will not dissolve or undergo any chemical reaction with the water. The gravel will remain suspended or settle at the bottom of the water due to differences in density. The water may become cloudy initially due to the particles of gravel being dispersed, but eventually, the gravel will settle down, leaving clear water on top.
The capacity of porous materials like sand and gravel to transmit water is referred to as hydraulic conductivity or permeability. These materials typically have high porosity and larger pore spaces, allowing water to flow through them more easily compared to finer materials like clay. The efficiency of water transmission in sand and gravel is crucial for various applications, including groundwater recharge, drainage systems, and construction. Overall, their ability to transmit water is significantly influenced by factors such as grain size, shape, and arrangement.
Yes, microbes can live in between gravel. The porous spaces in gravel can provide a habitat for microbes to thrive, as they have access to water, nutrients, and oxygen needed for their survival. Gravel can act as a biofilter, promoting the growth of beneficial microbial communities that help break down organic matter and maintain water quality.
You can determine if a rock is porous by observing if it has small holes or open spaces on its surface. Porous rocks will also generally have a high water absorption rate when placed in water, causing them to become heavier. Conducting a porosity test, such as measuring the volume of water absorbed by the rock, can also help determine its porosity.
it will die
when a vegetable is placed in very salty water, the vegetable becomes soft and collapses. Why does this happen?
