Accepted Answer

All of the answers are correct.

Answer

Neither liquids nor gases have a fixed shape.

Answer

Both liquids and gases have weaker intermolecular forces than solids

Answer

Both liquids and gases have the ability to flow.

Question 2

Accepted Answer

Between molecules

Answer

Between atoms of same compounds

Answer

Within molecules

Question 3

Accepted Answer

London Dispersion Forces

Answer

Dipole-Dipole Force

Answer

Hydrogen Bond

Answer

Ion-Dipole Force

Question 4

Answer

Ionic Bond

Question 5

Which among the following can form hydrogen bonds with water?

Accepted Answer

CH3OCH3

Answer

Na+

Answer

CH4

Answer

KCl

Question 6

Resistance of a liquid to flow

Accepted Answer

viscosity

Answer

vapor pressure

Answer

Capillary action

Answer

London force

Question 7

Which statement is true about the viscosity of a liquid?

Accepted Answer

The stronger the intermolecular forces, the more viscous the liquid.

Answer

The higher the temperature, the more viscous the liquid

Answer

The smaller the molecules, the more viscous the liquid.

Answer

The size of molecule and intermolecular forces does not affect viscosity of liquid

Question 8

Cohesion is:

Accepted Answer

an attraction between molecules of the same kind

Answer

a phenomenon that occurs only at the surface of water

Answer

a property that allows water to dissolve certain substances

Answer

exemplified by the action of water droplets sticking to your drinking glass

Question 9

Capillary action of water in a tube is the result of _____ being stronger than _____.

Accepted Answer

adhesion; cohesion

Answer

cohesion; adhesion

Answer

surface tension; cohesion

Answer

cohesion; surface tension

Question 10

Ice floats on water because

Accepted Answer

the molecules in ice are farther apart than the molecules in liquid water

Answer

there is oxygen dissolved in liquid water

Answer

water's surface tension is strong enough to support the ice

Answer

liquid water is less dense than ice

Question 11

Which of the following is not a property of water?

Accepted Answer

Hydrogen bonds exist only in the solid state.

Answer

It can dissolve ionic and polar molecules

Answer

It has a high surface tension

Answer

The solid state is less dense than the liquid state

Question 12

Suppose a solid ice melts due to increased temperature, what happens at particles based on the kinetic molecular theory?

Accepted Answer

Increase in temperature results increase in kinetic energy. The molecules will increase in speed of vibration and in turn increases the space between atom wherein solid ice slowly turns into liquid.

Answer

Temperature has no effect to solids and liquids, according to Kinetic molecular theory

Answer

Both A and B are correct

Answer

b.	Increase in temperature results decrease in kinetic energy. The molecules will increase in speed of vibration and in turn increases the space between atom wherein solid ice slowly turns into liquid.
