Properties Of Liquid

Question 1

can be described in terms of its physical state

Answer 1

Matter

Question 2

The three basic states of matter are?

Answer 2

Solid? Liquid and gas

Question 3

have particles with
strong intermolecular
forces such that their
particles are very close to
one another

Answer 3

Solid

Question 4

have intermediate
intermolecular forces.
This makes liquid particles
farther from one another
compared to those in
solids.

Answer 4

Liquid

Question 5

have particles that are
very far apart from one
another due to weak
intermolecular forces.

Answer 5

Gas

Question 6

can be attributed to the
intermolecular forces of attraction that hold the
molecules together in order to occupy a volume of a
certain space of a container

Answer 6

Properties of liquid

Question 7

These intermolecular forces of attraction are directly
related to the

Answer 7

Surface tension, viscosity, and vapor pressure

Question 8

the tendency of a fluid to acquire
the least possible surface area.

Answer 8

Surface tension

Question 9

Water striders can walk on water because of?

Answer 9

Surface tension

Question 10

the attraction between like molecules

Answer 10

Cohesion

Question 11

the attraction between unlike
molecules.

Answer 11

Adhesion

Question 12

the measure of a fluid’s resistance to flow.

Answer 12

Viscosity

Question 13

Liquids that flow easily have?

Answer 13

Low viscosity

Question 14

liquids
that do not flow readily have?

Answer 14

High viscosity

Question 15

Honey is a?

Answer 15

Viscous liquid

Question 16

Viscosity is also affected by?

Answer 16

Temperature

Question 17

When the temperature is high, the molecules have
more energy and it becomes easier to overcome the
IMFA. This leads to?

Answer 17

Lower viscosity

Question 18

For liquids, viscosity decreases with?

Answer 18

Increasing temperature

Question 19

for gases,
the viscosity increases with?

Answer 19

Increasing temperature

Question 20

the process where a fraction of the
kinetic energy of a liquid escapes from the surface to
enter the vapor phase

Answer 20

Vaporization

Question 21

The enthalpy of vaporization (4Hvap), also called the?

The heat required to induce this phase change.

Answer 21

Heat of vaporization

Question 22

as more molecules have
sufficient kinetic energy to overcome intermolecular
forces of attraction in the liquid.

Answer 22

Increased temperature

Question 23

since a
greater proportion of the liquid molecules are at
the surface.

Answer 23

increased surface area of the liquid

Question 24

as
the
kinetic energy needed to overcome
intermolecular forces of attraction is less, and more
molecules have enough energy to escape

Answer 24

decreased strength of intermolecular forces

Question 25

The enthalpy of vaporization is the quantity of heat
that must be ________ if a certain quantity of liquid is
vaporized at a constant temperature.

Answer 25

Absorbed

Question 26

the pressure exerted by a vapor in
equilibrium with its liquid phase in a closed system

Answer 26

Vapor pressure

Question 27

refers to the ability of a substance to
dissolve in a given amount of solvent at a specified
temperature.

Answer 27

Solubility

Question 28

If two liquids dissolve or mix together, they are called?

Answer 28

miscible liquids.

Question 29

If two liquids do not dissolve or mix together, they are
called

Answer 29

immiscible liquids.

Question 30

Substances or molecules that form interactions with
water are also described as

Answer 30

hydrophilic.

Question 31

primary IMFA in hydrophilic substances are?

Answer 31

Dipole-dipole forces and hydrogen bonding

Question 32

Substances or molecules that epel water are
described as

Soap and detergent molecules have

Answer 35

hydrophilic heads
and hydrophobic tails.
