Calculate and compare the albedo temperature of Mars to Venus. Then compare the two albedo temperatures the planet’s albedo temp
Kryger [21]

Answer:

The albedo temperature for Mars and Venus are 210K and 184 K respectively.Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.Thus there is a chance that Mars would have had life in their history.

Explanation:

The albedo temperature is given as

Te =\left [\dfrac{L(1-a)}{ (16\pi \sigma D^2}\right]^{1/4}

Here

L = Solar luminosity = 3.846*1026 W m-2 K-4

D = distance from Sun

σ = the Stefan-Boltzman constant = 5.6704 * 10-8 W

a is the albedo constant whose value for Mars is  0.250 while for  Venus it is 0.900

So the albedo temperature is given as

Venus: 184 K

Mars: 210 K

The black body temperature is given as

Te =\left [\dfrac{L}{ (16\pi \sigma D^2}\right]^{1/4}

By substitution of the values, the black body temperature for Venus and Mars are as

Venus: 327 K

Mars: 225 K

Mars albedo temperature is closer to its black body temperature such that the Venus has more albedo.

Thus there is a chance that Mars would have had life in their history.
