It hides in shadows. It is said that if Gengar is hiding, it cools the area by nearly 10 degrees Fahrenheit.

Last Week, there was an entry on Gengar where we analyzed why Gengar lowers the temperature of the room. To which solkatspacekitties replied:

Well, let’s figure out what happens when you give Gengar a hug. Following the same process as before, and assuming the only heat transfer is between you and Gengar (no heat lost to the air),

Solving for Tf this time,

We now have all the information we need to find what your temperature will be after you give Gengar a hug. Using the following values:

m(G) = 40500 g (taken directly from pokedex)
c(G) = 3.5 J/gC (same assumption we made before)
T(i,G) = -96.8 C (found in last post)
m(y) = 62000 g (average mass of a human)
c(y) = 3.5 J/gC (specific heat of human)
T(i, y)= 37 C (average human body temperature)

If you hug Gengar, your body temperature will drop to -16 degrees Celsius, or 3.2 degrees Fahrenheit. You would die.

I think its safe to assume that Gengar uses a lot of energy, more than he can get from eating or breathing like we do. Therefore, Gengar uses heat transfer like this to survive.

That means no hugs. 😦
