What else can I help you with?
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?
Initial water content in the soil sample can be calculated using the initial mass and final mass after drying. Initial water content = (Initial mass - Final mass) = 1.38 kg - 1.13 kg = 0.25 kg. This is the mass of water in the soil sample.
What sampling method would you use to find small animals in leaf litter ir soil sample?
sweep net
How would soil sample be described?
Crumbly, bits of earth.
Which soil sample would lose water more?
The soil sample with smaller particles tends to hold water better than the soil sample with larger particles. This is because smaller particles have higher surface area and can retain more water due to capillary action. Therefore, the soil sample with larger particles would likely lose water more quickly.
Is a typical soil sample an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.A homogenous mixture means that all components of the mixture are equally distributed throughout the entire mixture. Soil, then, would not be a homogenous mixture. Every time one takes a sample of a soil mixture and analyzed it, it would have a different make-up then other samples taken from the soil mixture. One would seldom be able to get two samples that had the same make-up.No, soil is heterogeneous.No. A mixed sample, by Nature, is heterogenous and so may not also be a homogenous (pure) substance.
A scientist studying humus would most likely examine a sample of what?
Soil
A typical soil sample is an example of a homogeneous mixture?
No, a typical soil sample is heterogeneous.
What tool would you use for finding the mass of the soil?
A scale or balance would be the appropriate tool to use for finding the mass of soil. Place a container on the scale, tare it to zero, then add the soil to determine its mass.
How would this soil sample be described?
To describe a soil sample, one would typically analyze its texture, color, pH level, organic matter content, and nutrient composition. This information can help determine the suitability of the soil for various purposes such as gardening or farming.
Would a soil sample from a temperate deciduous forest be more or less nutrient - rich than a soil sample from a tropical rain forest?
A sample of soil from a temperate deciduous forest would be less nutrient-rich than the soil from a tropical rain forest, because the moisture would continually break down mulch to support a bigger variety of organisms.Tropical rain forests naturally support more species than a deciduous forest too.
Which sampling method would you use to find small animals in leaf litter or in a soil sample?
To find small animals in leaf litter or soil samples, I would use a combination of stratified random sampling and pitfall traps. Stratified random sampling allows for targeted collection in different types of leaf litter or soil layers, ensuring a representative sample. Pitfall traps can be effective in capturing small animals as they fall into the traps while moving through the leaf litter or soil, providing a non-invasive way to collect data on the fauna present.
If a soil sample is 60 sand particles and has 30 millon particles of soil how many of those soil particles are sand?
If the soil sample has 30 million particles of soil and 60 of those particles are sand, then the number of soil particles that are sand is 60. Sand particles represent 0.000002% of the total particles in the soil sample.
