Determine the albedo value of Pluto.
Answer to Problem 1P
The albedo value of Pluto is
Explanation of Solution
Given information:
The average orbital diameter of Pluto is 39.2 times of the earth.
Mean surface temperature
Pluto has no atmosphere.
Calculation:
The solar flux at the outside of the earth’s atmosphere
Find the Insolation of Pluto
Let the albedo is a.
The value of Stefan Boltzmann constant is
The expression to find the temperature (T) is given below:
Therefore, the albedo value of Pluto is

- One geoengineering solution to prevent global warming is to increase Earth’s albedo by adding particles to the stratosphere that can reflect sunlight or increasing cloudiness over the oceans. By how much does the albedo have to change to reduce the Earth’s temperature by 1 degree K? What is the corresponding energy difference in W/m2?

It is the region in which phyto- plankton live and can undergo photosynthesis. The depth of the photic zone varies depending on how murky the water is — “murkiness” is caused by, for example, tiny particles of sediment that absorb light. The aphotic zone is defined as being the depth beyond which more than 99% of the light from the surface has already been absorbed.arrow_forwardIf specific gravity of Glycerin is 1.3 and the specific gravity of Mercury is 13.6, what value of X will produce 21mmHg reading at A.
