Worksheet chapter 2 Flashcards
Which of the following substances has the highest specific heat value?
a. land b. ice c. water
water
Due to its low specific heat value, this substance will heat and cool quicker than the other two.
a. land b. ice c. water
land
Name the three phase change processes of water that take heat energy from the environment.
- _melting ____________ 2. _evaporation_________ 3. _sublimation________
Name the three phase change processes of water that release heat energy to the environment.
- _freezing____________ 2. _condensation________ 3. _deposition__________
How many calories of energy are required to evaporate 3 grams of water?
3 X 600 = 1800
How many calories of energy are required to melt 8 grams of ice?
8 X 80 = 640
How many calories of energy are released to the environment when 5 grams of water vapor condense into water droplets?
5 X 600 = 3000
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.
condensation
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
T
The surface of the sun is very hot at 6000 Kelvin. Using Wien’s Law, this temperature would emit a maximum wavelength found in the ___________________ category.
b. visible light
The surface of the earth is much cooler at 288 K. Using Wien’s Law, this temperature would emit a maximum wavelength found in the ___________________ category.
infrared radiation

d. shortwave radiation e. both (b) and (d) are correct
e. both (b) and (d) are correct
Another name for infrared radiation is:
a. ultraviolet radiation b. terrestrial radiation c. longwave radiation
d. shortwave radiation e. both (b) and (c) are correct
e. both (b) and (c) are correct
Greenhouse gases in the atmosphere absorb and re-emit this type of radiation.
a. ultraviolet radiation b. solar radiation c. infrared radiation
infrared radiation
The presences of ozone (O3) in the Stratosphere absorbs this type of radiation.
a. ultraviolet radiation b. solar radiation c. infrared radiation
a. ultraviolet radiation
This type of radiation can move freely through the atmosphere because it is not absorbed by the greenhouse gases?
a. ultraviolet radiation b. visible light c. infrared radiation
visible light
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.
atmosphere
Solar or shortwave
infrared or longwave

The earth has a Greenhouse Effect because the earth’s _____atmosphere_____ is a selective
absorber of radiation. __Solar or shortwave_ radiation from the sun is allowed through the atmosphere
whereas some of the outgoing infrared or longwave radiation from the earth’s surface is absorbed and
re-emitted by the various ___greenhouse_________ 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.
