The standard enthalpy of combustion is the enthalpy change when one mole of a substance completely reacts under standard thermodynamic conditions (although experimental values are usually obtained under different conditions and subsequently adjusted). By definition, combustion reactions are generally strongly exothermic and so enthalpies of combustion are generally strongly negative.
It is commonly denoted as or . When the enthalpy required is not a combustion, it can be denoted as . Enthalpies of combustion are typically measured using bomb calorimetry, and have units of energy (typically kJ); strictly speaking, the enthalpy change per mole of substance combusted is the standard molar enthalpy of combustion (which typically would have units of kJ molā1).
imagine this guy..isn't sponsored and rides a single pivot out dated bike. if u sent this to ANY company, i can almost assure you they would send you a free bike and sponsor you.
Thanks man. I should get on that. I race moto but love mountain biking. And tricking mtb is so sick and the learning curve has been huge. Ogio and Dragon Goggles help me out, but that's for moto.
A very rarely,if ever seen trick on a MTB,especially a big DH rig like yours m8,so big props for that Kris,you do indeed have balls of steel,and that is indeed POD and it would be a travesty if it isn't in the May top 5 POD's.Brilliant tsunami Kris.And easily POD. Gringo.
Finally. A KOD! I was actully dreaming about attempting to do it. The full suspension bike is the way to go. On a HT you wont get that power to pull yourself together on the bike. Well atleast if you dont have those pins cam mccaul uses when he does his superflip or any other FMX riders.
well done. POD!
this foster guy, you have impressed me dude, that is one of the best extensions ive seen in my 5 years of dirtjumping. i'm a moto dude and thats moto style, awesome i giv eyou all the props i can homie
man how do you get back from that extension thats ridiculous, some next level shit man, i really hope you landed this and didnt just eat shit but got the picture in time, a video would be dope id like to see how you get back
This is some random girl, Who trolls around, And listens to people/scroll's through comments, and decides weather or not to say something dirty, depending on what the person has said.
How should I know? There is so many sick FMX tricks which are not performed on a bike becouse people still think they are not possible. We need people like Kris who show them how wrong they are.
I have the same bike. I always bitch about wanting a better bike, and here you are, way better than me, riding the same thing... I'm sure you'd have no problems getting sponsored!
