GY 101 Lab Final ACTUAL UPDATED Questions and CORRECT
Answers
1. Fahrenheit Mainly used in the US
Boiling point of water: 212 degrees
freezing point of water: 32 degrees
absolute zero: -460 degrees
2. Celsius Metric unit for measuring temperature (used everywhere else along with kelvin)
freezing point of water: 0 degrees
boiling point of water: 100 degrees
absolute zero: -273 degrees
3. Kelvin SI unit for temperature (used everywhere else along with celsius)
boiling point of water: 373.15K
freezing point of water: 330K
absolute zero: 0K
4. conversion for F = ((9*C)/5) + 32
celsius to Fahren-
heit
5. conversion for C = K - 273
Kelvin to celcius
6. conversion for C = (5*(F-32))/9
Fahrenheit to cel-
sius
,7. conversion for K=C+273
celsius to kelvin
8. Air pressure the pressure exerted by the weight of air above
average air pressure at sea level is 1013.2 mb or about 1 kilogram per square inch
(psi)
9. atmospheric commonly measured in millibars (mb)
pressure
10. 1 mb = 0.014 pounds per square inch (psi)
11. 1 psi = 703.1 kilograms per square meter
12. 1 psi = 0.07031 kilograms per square centimeter
13. Specific heat the heat required to raise the temperature a unit mass of a given substance by a
given amount (usually one degree)
written as (Cp) and measured as J/g degrees Celsius or J/g degrees Kelvin
14. Cp (specific heat) 4.184 J/g degrees Celsius
of water
15. Q=mCpT Q= Heat energy
m= mass (measured in g)
Cp= specific heat
T= change in temperature
16. time series display values against time
graphs
time is always plotted on the x-axis
is used to show how data (temp., rainfall, wind speed, etc. changes over time
, data points are connected with a line
17. scatterplots used to show the relationship (or lack thereof) between two variable
the relationship between the variables is called the correlation
independent variable plotted on x-axis and dependent variable plotted on y-axis
you will be able to identify if there is a positive, negative, or no correlation
18. Latitude lines run parallel to the equator called "parallels"
northern hemisphere is 0-90 degrees North
southern hemisphere is 0-90 degrees South
shorter lines at the poles
19. Important lines Equator: 0 degrees
of Latitude North Pole: 90 degrees North
South Pole: 90 degrees South
Tropic of Cancer: 23.5 degrees North
Tropic of Capricorn: 23.5 degrees South
Arctic Circle: 66.5 degrees North
Antarctic Circle: 66.5 degrees South
Latiiudes of the tropic are the farthest north and south at which the sun can be
directly overhead
20. Longitude Lines run vertically between the north and South Pole
called "meridians"
measured 0-180 degrees West or East
farther apart as you get closer to the equator
