What is the percentage of empty volume in a rock or sediment called?
It is called its porosity.
How does porosity arise in materials?
Like how poruous it is (how easily water goes through it)
What is rock porosity?
Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%.
The volume of a sample of water is 20cm3 the mass of?
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
Is porosity a measure of the volume or open space in rocks and unconsolidated geological materials such as alluvium?
true
What is the percentage of empty volume in a rock or sediment called?
It is called its porosity.
What is the process in which the volume and porosity of a sediment is decreased by the weight of overlying sediments?
The process is called compaction.
What is the formula for calculating percent porosity?
Place Sediment in a cylinder Vt = A=πr^2 of sediment Fill a cylinder with water and weigh = Wm Water mass Add water slowly to sediment until saturated Weigh remaining water = Wmr Water mass remaining Subtract weight of Wm - Wmr =Vv (volume of water added to the sediment) Divide Vv by Vt Multiply by 100 Porosity as a %
When A dry soil sample has a volume of 500 mL After 400 mL of water are added to the soil the soil becomes saturated with 150 mL of surface water left on top What is the porosity of the soil?
the porosity is 50%
A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil the soil becomes saturated with 150 mL of surface water left on top. What is the porosity of the soil?
the porosity is 50%
How do you calculate the porosity for rhombohedral packing?
Porosity= Volume of void space/ Total volume of the solidThis is a good way for soil, If you have the initial volume of the soil then all you have to do to find the void space is saturate it with water. As long as you know the weight different between before and after saturation you can find the void space because we know that water's density is about 1g/cm^3.So,Porosity= ((mass of saturated soil - mass of original soil) Density of water) / Volume of original soilThis also works.
The percentage of a rock's total volume taken up by pore space is called the?
porosity of the rock.

What is the volume of open pore spaces in a rock?
This is known as porosity.
How do you test porosity of pumice?
Several methods can be employed to measure porosity, including the volume/density method (pore volume = total volume - material volume), water saturation method (pore volume = total volume of water - unsaturated water), water evaporation method (pore volume in cubic centimeters = weight of saturated sample in grams - weight of dried sample in grams), mercury intrusion porosimetry (several non-mercury intrusion techniques have been developed due to toxicological concerns, and the fact that mercury tends to form amalgams with several metals/alloys), and nitrogen gas adsorption (nitrogen gas adsorption in pores is measured either by volume or weight. This technique is suitable for materials with very fine pores).

What is the volume of voids of open space in a rock or unconsolidated material?
Porosity is the volume of open spaces in rock or soil.
