The vertical sequence of the layers of soil is called a soil ____?

1 answer:

5 0

Soil profile
Soil profile is the vertical sequence of the layers of soil. Furthermore, there are actually six layers of the soil which involves the organic matter, -where most humus is present-, surface soil, the subsoil, the parent rock, and the bedrock as the innermost and core layer of the soil. In addition each soil layer has three to four soil horizon. These horizons are the physical features of the soil, mainly the texture, color and composition.

Carbon dioxide (CO2) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 30 lbf/in2, and a volume of 1.6 f

solong [7]

Answer:

The answer to this question can be given as:

The initial pressure P= 30 lbf/in2

The initial temperature T1=80°F.

The initial volume=final volume V= 1.6 ft3.

Final temperature T2=500°F

Heat transfer Q=-2.6 Btu.

pressure (P) (lbf/in2) change into lbf/ft2

P=30 lbf/in2=4320lbf/ft2.

Temperature (T1) °F change into °K

temperature T1=80°F=539.67 °K

Ideal gas formula:

M=PV/RT1. where T1=initial temperature.

M=4320*1.6/35.114*539.67.

M=0.364749 lb Mass at Carbon dioxide (CO2).

DQ=DU+W second law.

-2.6=MCV(T2-T1)+ W

-2.6-(0.364749*1.6(500-80))=W

W=-27.111 b+u am----> work done.

Explanation:

The explanation to this question can be given as:

Firstly we write the equation that is given in the question like, pressure, volume, gas constant, temperature. Then we covert the pressure and temperature into there possible values. Then We apply the formula of Ideal gas that is M=PV/RT1. where M is the mass, P is the pressure , V is the volume , R is the gas constant (0.08206 L·atm·K−1·mol−1) and T1 is the initial temperature. Then we use the second formula that is DQ=DU+W. Where DQ= Heat transfer, DU=MCV(T2-T1)and W= work. It is used for finding work.

What is mean by saturated solution and unsaturated solution

zvonat [6]

•Saturated Solution: A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution.

Example: A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles.

•Unsaturated solution: It is a solution in which more of solute can be dissolved at a given temperature. In this, addition of solute is possible till the solution reaches the point of saturation.

Example: Salt dissolved in water even sugar dissolved in water is an Unsaturated solution if the quantity of dissolved Salt/Sugar is below the saturation point.
