Worksheet chapter 2

Question 1

Which of the following substances has the highest specific heat value?
a. land b. ice c. water

Answer 1

water

Question 2

Due to its low specific heat value, this substance will heat and cool quicker than the other two.
a. land b. ice c. water

Answer 2

land

Question 3

Name the three phase change processes of water that take heat energy from the environment.

Answer 3

1. _melting ____________ 2. _evaporation_________ 3. _sublimation________

Question 4

Name the three phase change processes of water that release heat energy to the environment.

Answer 4

1. _freezing____________ 2. _condensation________ 3. _deposition__________

Question 5

How many calories of energy are required to evaporate 3 grams of water?

Answer 5

3 X 600 = 1800

Question 6

How many calories of energy are required to melt 8 grams of ice?

Answer 6

8 X 80 = 640

Question 7

How many calories of energy are released to the environment when 5 grams of water vapor condense into water droplets?

Answer 7

5 X 600 = 3000

Question 8

Thunderstorms, hurricanes, and low pressure systems are three weather events that need water vapor to develop and strengthen. Name the phase change process of water that is occurring within these weather events that will release a considerable amount of energy for their development.

Answer 8

condensation

Question 9

Snow is ice (solid). The process to melt snow (solid → liquid) will slow down the potential warming of the atmosphere because the process to melt snow will take energy from the environment. T or F

Answer 9

T

a. ultraviolet radiation b. visible light c. infrared radiation

Answer 17

visible light

Question 18

The earth has a Greenhouse Effect because the earth’s _____?_____ is a selective
absorber of radiation. __?___ radiation from the sun is allowed through the atmosphere
whereas some of the outgoing ___?___ radiation from the earth’s surface is absorbed and
re-emitted by the various ___?_________ gasses in the atmosphere which will keep the earth at
a comfortable 59°F versus 0°F if the earth did not have an atmosphere.

Answer 18

atmosphere
Solar or shortwave
infrared or longwave
greenhouse
