Water that penetrates through the pores of the clay vessel is evaporating; evapora-tion is a phenomenon with absorption of energy, so that it is a slight cooling effect on the water content of the pot.
Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
Porous rocks absorb water. Anything that can absorb water would not be good at containing it.
The WHO guideline expects a controlled amount of chlorine to be placed in the drinking water.
Asbestos is a porous material and can absorb water.
Porous means that there are gaps in the particles that allow water through. Porous aluminum is not watertight.
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
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..
Non-porous rocks are solid materials that do not allow water or other fluids to pass through them due to the absence of interconnected pore spaces. This lack of porosity prevents the storage or movement of fluids within the rock, making them impermeable. Examples of non-porous rocks include granite, basalt, and marble.
because its porous
anything that is porous is capable of absorbing water
