Answer:
Water molecule has hydrogen bonding and surface tension
Explanation:
Intermolecular behavior of water is different from that of the intermolecular force of oil because water molecule is polar in nature while oil molecule is non polar. Dur to polar nature, water molecule has high surface tension which keep its atoms intact. Also the water molecule being polar also exhibit hydrogen bonding between hydrogen (+ive) and oxygen atom (-ive)
Explanation:
Compound: a substance that is made up of more than 1 type of atom bonded together Example: H2O
Mixture: combination of two or more elements or compounds not chemicaly bonded together. example: Sugar and salt in one container
elements pure substance of an atom. Example: hydrogen
Percent Composition by Mass. Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.

Answer:
D.
Explanation:
Im not quite sure if its correct or not
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 = ..........2
bulk unit wt =
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
