Answer is given below
Explanation:
given data
weight = 6N
temp = 105° C
weight reduced = 5N
solution
weight of container is 1N
SO W = (6-1) = 5
And Wd = 5 - 1 = 4
so
moisture content is
moisture content = 
.......1
moisture content = 
moisture content = 25%
and
as we know density of soil soild = 2700 kg/m³
density of water = 1000 kg/m³
and sp gravity of soil = 
= 2.7
so
now we get here bulk unit weight
bulk unit wt = ![Yw \times [\frac{G+e}{1+e}]](https://tex.z-dn.net/?f=Yw%20%5Ctimes%20%5B%5Cfrac%7BG%2Be%7D%7B1%2Be%7D%5D)
..........2
bulk unit wt = ![9.01 \times [\frac{2.7 + 0.675}{1+0.675}]](https://tex.z-dn.net/?f=9.01%20%5Ctimes%20%5B%5Cfrac%7B2.7%20%2B%200.675%7D%7B1%2B0.675%7D%5D)
bulk unit wt = 19.766 KN/m³
and
so dry unit wt will be
dry unit wt = 
..............3
dry unit wt = 
dry unit wt = 15.813 kN/m³
Answer:
B
Explanation:
A. Is wrong
This definition in this option does not fully define what an open system entails. It only gave a one sided definition of the phenomenon on ground
B is correct
In an open system, matter and energy should be free to leave
C is incorrect
This is clearly a one sided definition like A and should not be taken serious
D is incorrect
D is talking essentially about what a closed system is
Answer:
+and+
Explanation:
positive is helps to the right and wrong way
<span>Evaporation is the process of atoms or molecules in a liquid, or solid state (depending on the state of the substance sublimes) gains enough energy to become gaseous. </span>
Compound is formed when two or more chemical elements are chemically bonded together. elements are made of atoms
