More Than You Ever Wanted to Know About Mechanical Engineering: Latent Heat

Let’s look in detail at the process of boiling a pure substance.

We’ll start out with a compressed liquid. We’ll say it’s water at 25 deg C. Moreover, let’s say it’s contained in a cylinder with a piston so that the pressure inside the cylinder is always at atmospheric pressure.

If we start heating up the cylinder, the water inside will expand slightly. The pressure will remain constant as the piston moves with the water’s expansion. Once we get to 100 deg C, the water exists as a saturated liquid - any additional heat will cause it to vaporize.

If we keep adding heat to it, things get interesting. The water will start to boil. It’s volume will increase drastically, but its temperature will remain the same. All the energy you’re putting into it is going into the phase change. The amount of energy it takes to go from a liquid to a vapor is called the latent heat of vaporization. (Similarly, the amount of heat it takes for a solid to melt into a liquid is the latent heat of fusion.)  So while the water in your cylinder is in the process of boiling, it exists as a mixture of saturated liquid and saturated vapor. Its temperature will remain at a constant 100 deg C throughout the process. Although its apparent volume will increase, its specific volume - the volume per unit mass - will also remain constant.

Once all the water has been vaporized, if you continue adding heat to the cylinder, the water will start to rise in temperature again and its specific volume will start to increase. In this state, it exists as a superheated vapor.

The entire process we just described looks like this.

Note that this show temperature vs. specific volume for only one pressure - if we varied the pressure as well, things would look quite different. The interdependence of temperature, volume, and pressure will be important in our analysis of thermodynamic processes.

Unless it’s mad, passionate, extraordinary love, it’s a waste of your time. There are too many mediocre things in life. Love shouldn’t be one of them.

What The Box? Is a very cool multiplayer shooter in which all the players are boxes, and are identical to the thousands of ordinary cardboard boxes that randomly litter the levels – so you can literally hide in plain sight, movement is the only thing that will give you away!  

Snake’s been hogging the limelight for too long, it’s about time the cardboard box got it’s own game!

My scanning process

Hello everyone! I’ve been sharing a lot of scans on this Tumblr and most of them are my scans. I wanted to show you my process because it’s probably a bigger task than you think!

First, I buy some artbooks, mostly on Ebay and Amazon (.com & .co.jp). Usually, manga/anime artbooks come directly from Japan and movies/video games artbooks come from the USA or UK.

Then… I wait. When the book comes from Japan it usually takes a bit more than 3 weeks, for the USA an average of 2 to 3 weeks, and from the UK it’s pretty fast (I live in France).

Btw, if someone’s interested in learning how to code, Codecademy is a great (and I mean not boring) way to learn some basics.

And listening to this song on repeat one, I finished this in two days! :D

It’s not much, but it’s a start! 😸

In Which Diversity Isn't a Myth

Ok. I’m tired of the typical vampire, werewolf and fairy.I’m also tired of the occidental-centrism in mythology. Hence, this list. 

I tried to included as many cultural variants as I could find and think of. (Unfortunately, I was restricted by language. Some Russian creatures looked very interesting but I don’t speak Russian…) Please, add creatures from your culture when reblogguing (if not already present). It took me a while to gather all those sites but I know it could be more expansive. I intend on periodically editing this list. 

Of note: I did not include specific legendary creatures (Merlin, Pegasus, ect), gods/goddesses/deities and heroes.

  • Dragons

  • Little creatures (without wings)

  • Creatures with wings (except dragons)

  • References on Folklore and Mythology Across the Globe
  • References on writing a myth or mythical creatures

(I have stumbled upon web sites that believed some of these mythical creatures exist today… Especially dragons, in fact. I just had to share the love and scepticism.)

Dokkaebi/도깨비 in Korea are common creatures that come up in stories that don’t seem to be on the list of tiny creatures… They may be in the goblin lists though

Also useful for designing original pokemon.

Mercury(II) Thiocyanate:  The Pharaoh’s Serpent

Mercury(II) thiocyanate (Hg(SCN)2) is an inorganic chemical compound, the coordination complex of Hg^2+ and the thiocyanate anion. It is a white powder. It will produce a large, winding “snake” when ignited, an effect known as the Pharaoh’s Serpent.  The first synthesis of mercury thiocyanate was probably completed in 1821 by Jöns Jacob Berzelius:

  • HgO + 2 HSCN → Hg(SCN)2 + H2O 

Evidence for the first pure sample was presented in 1866 prepared by a chemist named Otto Hermes. It is prepared by treating solutions containing mercury(II) and thiocyanate ions. The low solubility product of mercury thiocyanate causes it to precipitate from solution. Most syntheses are achieved by precipitation:

  • Hg(NO3)2 + 2 KSCN → Hg(SCN)2 + 2KNO3 

Mercury thiocyanate was formerly used in pyrotechnics causing an effect known as the Pharaoh’s serpent or Pharaoh’s snake. When the compound is in the presence of a strong enough heat source, a rapid exothermic reaction is started which produces a large mass of coiling serpent-like solid. An inconspicuous flame which is often blue but can also occur in yellow/orange accompanies the combustion.
