Media The Science Of The Mage's Meteor

For assassin you could cover how much force it takes to levitate someone in the air and keep them there for two whole seconds, while being able to maintain full control of their direction, while using only a dagger and your arm strength. In other words, multihit

 

I am probably going to do assassin and also vanish will be fuuuun to do.

I forgot to say that I'm assuming a 75% energy waste, I am stupid.

 

Why do you throw out random jargon instead of literally telling me which laws of thermodynamics you employed and you know, tell me which equations you used. What numbers did you use. How did you arrive at half a ton of TNT equivalent.

 

I did tell you, firstly I need to point out as I stated before I assumed a 75% energy waste thus increasing the total energy required, secondly I may point out, the fact of the matter is that we are talking about a system where there is no flame causing it to burn. Instead we have a system where we are getting grass from room temperature to its auto ignition point, due to the water requiring vaporization I used the auto ignition point of paper. This is not a situation you will come across in everyday life. So I can understand you being wary and questioning. Also I may point out that due to imperfect conversions and transfers of energy there always will be energy waste. Next thing is that due to it not being a isolated system the second and third due apply, this is not an isolated system due to the huge meteor being the cause of the heat. But when the grass does catch on fire then we can look at it as a isolated system and see that the entropy does increase. But nonetheless due to it being not an isolated system most of the laws of thermodynamics do not apply here. Read the wording on the laws, they specifically look at isolated systems.

 

Basic formula I used to calculate energy required to cause grass to ignite.
pi*height of grass (.0625 m)*radius (7 meters/ 7 blocks)/3 (to account for space that is not grass)*density of grass (395.71 kg/m3)=1269.06 kg of grass. grass is 70% water and 30% lignin resulting in 888.342 kg of water and 380.718 kg of lignin. The auto ignition temperature of grass is similar to paper at around 233 Celsius or 451 Fahrenheit. Assuming we are using meteor at room temperature the grass needs to have a temperature increase of 210.278 degrees Celsius. So (888.349 kg*4.186 kilo joules(waters heat capacity)*210.278)+(380.718 kg*1.1 kilo joules(lignins heat capacity)*210.278) = 870008132.342492 joules. Then assuming a 75% energy waste we get 3.48 gigajoules, Yes I messed up on the conversions before, don't hate me. I admit I screwed up.

Also I screwed up in my last comment. Actually there is a internal system when considering the Meteor is the thing that causes the grass to ignite so this is in a internal system. And the entropy does increase and lastly the total energy in the closed system does not change asides from entropy. But some is changed to heat while most stays kinetic and causes the meteor to explode because of the every action has an equal and opposite reaction stuff.
