What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
Why is the surface mars red?
Because of the amount of iron in the soil. When iron oxidizes, it becomes red, like rust on a bicycle left outside for too long. So since the iron in Mars' soil has oxidized, the soil is red.
Is Mars' soil blue?
No, it is a red-orange color due to the deposition of iron (or, due to the high iron content of the soil), hence the name "The Red Planet"
A saturated soil sample has a mass of 1.38kg and a volume of 0.6 liters. After dried in a oven for 24 hours the mass of th soil sample is 1.13kg. calculate mass of water?
Apparently, the mass of water is simply the difference between saturated soil mass and the dried soil mass and this is 0.25 kg. - grade
Can soil and water be separated by a filter?
A paper filter will allow water to slowly pass through, leaving the soil particles behind.
What physical property would allow you to seprate a mixture of iron filings and soil?
Magnet
How do you test for iron in a sample of soil?
Hold a magnet up to it.
Is a soil magnetic material or a non magnetic material?
it generally depends on the soil content~if it is rich in iron or some other magnetic metals it will magnetize but if it don't it won't..soil is non-magnetic but iron filings in it are magnetic
How do you separate iron filings and plastic and cooking oil and salt and soil and food scraps from water?
You use a magnet to get the iron filings out, then you add water to the rest. Create a funnel out of a paper cup, pour it through which you would then be able to get the poppy seeds off the funnel. Then you would boil the water to separate the salt from the water.
A typical soil sample is an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.
How does iron get into food?
Iron occurs naturally in the soil. (->) means consumed or eaten or used. Iron in the soil -> Plants -> Us Iron in Soil -> plants -> animals -> us
What are the advantages of conducting an experiment on undisturbed soil sample compared to disturbed soil sample?
A disturbed sample is one in which the structure of the soil has been changed sufficiently that tests of structural properties of the soil will not be representative of in-situ conditions, and only properties of the soil grains (e.g., grain size distribution, Atterberg limits, and possibly the water content) can be accurately determined. An undisturbed sample is one where the condition of the soil in the sample is close enough to the conditions of the soil in-situ to allow tests of structural properties of the soil to be used to approximate the properties of the soil in-situ.
What is the best speed to separate a soil sample in a centrifuge?
Very high speed is the best speed to separate a soil sample in a centrifuge.
How can porosity be measured?
Porosity is measured by taking a sample of the soil. The sample is then tested to measure the speed of water passing through the soil.
How do you neutralize soil after fertilized?
To neutralise a sample of soil, you must determine the pH of the soil sample either acidic or alkaline. Add lime (e.g. Limestone) to acidic soil to neutralise it. And add sulphur to alkaline soil which will neutralise it.
What is the general appearance of the soil sample?
Brown.
The amount of each kind of soil particle in a sample determines the blank of the soil?
Dirt
