Greenhouse Gasses
What is the most common greenhouse gas?
CO2 (carbon dioxide)
When a molecule absorbs energy how does it move?
Faster
5,600,123 cm in scientific notation
5.6 x 10^6 cm
What country have we been learning about in regard to its ice sheets melting
Greenland
What is the second most common greenhouse gas?
CH4 (methane)
It slows down
In the equation "Q = 80 x m" what does 80 represent
the amount of energy it takes to melt 1 gram of ice
Why does sea level only rise when ice on land melts and not in water?
Displacement of sea ice
What are the two ways CO2 releases energy after absorbing a photon of light?
Bumping into another molecule or releasing a photon
Energy can not be created or destroyed
Solve this problem. 1005 cal of energy is added to a large chunk of ice. How much of the ice melts?
12.5625 grams
Why is melting occurring at the bottom of the illusuat glacier?
dense warmer sea water was pushed down by cooler fresh water
What makes green house gasses different from other gasses? Why can they absorb heat?
Dipole Moment
What is the second law of thermodynamics
Closed systems trend toward disorder
What do each of the variables in this equation mean
"Q = c x m x ΔT"
Q = Energy
c = specific heat capacity
m = mass
ΔT = change in temperature
Explain the two proposed solutions to prevent the melting of ice and how they affect heat transfer
Heat is moved away from the ice in some capacity.
What was the concentration of CO2 in the atmosphere at the beginning of the industrial revolution and what is it now.
280 and 425 ppm CO2
What is a calorie?
The amount of energy required to raise the temperature of water 1 degree Celsius.
2056 J of energy are added to a 314 g piece of iron that has a specific heat capacity of 0.451 J/g°C
14.52 °C
