$$Q = m \times c \times \Delta T$$

Question 1

Which type of bond is primarily responsible for the unique properties of water, such as high surface tension and high specific heat?

Accepted Answer

Hydrogen bonds

Question 2

Why does ice float on liquid water?

Accepted Answer

Stable hydrogen bonds keep water molecules of ice farther apart than water molecules of liquid water.

Question 3

Which emergent property of water is most important for moderating Earth's climate?

Accepted Answer

High specific heat

Question 4

A spider can walk across the surface of a small pond due to which property of water?

Accepted Answer

Surface tension

Question 5

Which statement best explains why water has a high heat of vaporization?

Accepted Answer

Water molecules are held together by abundant hydrogen bonds.

Question 6

What is the main reason lakes do not freeze solid in winter, allowing aquatic life to survive?

Accepted Answer

Ice is less dense than liquid water and floats, insulating the water below.

Question 7

Which of the following best describes the polarity of a water molecule?

Accepted Answer

It has a negatively charged oxygen atom and positively charged hydrogen atoms.

Question 8

Which property of water allows it to dissolve many ionic and polar substances?

Accepted Answer

Its polarity

Question 9

Which of the following is NOT an emergent property of water?

Accepted Answer

High density of solid compared to liquid water

Question 10

What is the equation for calculating the amount of heat required to raise the temperature of a given mass of water?

Accepted Answer

$$Q = m 	imes c 	imes \Delta T$$

Question 11

Which process describes the conversion of water from a liquid to a gas?

Accepted Answer

Evaporation

Question 12

Which of the following best explains why water has a high specific heat?

Accepted Answer

Water molecules are held together by hydrogen bonds that require more energy to break.

Question 13

Which property of water is most responsible for its ability to climb up the stem of a plant against gravity?

Accepted Answer

Cohesion and adhesion

Question 14

A solution in which water is the solvent is called a(n) ______ solution.

Accepted Answer

Aqueous

Question 15

Which of the following effects can occur because of the high surface tension of water?

Accepted Answer

A spider can walk across the surface of a small pond.

Question 16

Which statement is true about the density of water and ice?

Accepted Answer

Liquid water is denser than ice.

Question 17

Which of the following is a direct result of water's polarity?

Accepted Answer

Water can dissolve ionic compounds.

Question 18

Which of the following best describes the charge distribution in a water molecule?

Accepted Answer

The oxygen atom is partially negative, and the hydrogen atoms are partially positive.

Question 19

Which property of water is most important for its role as a universal solvent?

Accepted Answer

Its polarity

Question 20

Which of the following statements about water molecules is correct?

Accepted Answer

Hydrogen bonds form between the hydrogen atom of one water molecule and the oxygen atom of another.
