you guys should do a poll! who is your favorite scientist! :)

I once worked with a guy that was the emotional equivalent of an endothermic reaction. He would walk into a room and suck all the fun out of it. ;-)

show us how to detonate Ammonia Nitrate :D

14.9 degrees that's a pretty cold lab

@AznAlacran the thermal energy absorbed goes into the process of breaking bonds in the reactants - the energy is used up, it is not still there once the products are made. When bonds are made (i.e. forming the products) energy is released.

In an endothermic reaction the amount of energy released from bond formation is less than that absorbed to break the bonds. Overall, energy is absorbed, decreasing the temperature.

Hope that helps; send me a message if you want more explanation :)

Great video but I really don't understand an endothermic reaction. If it absorbs thermal energy wouldn't it become warmer because it's absorbing heat?

less than 15 degrees? this lab is pretty cold!

I though that the forward reaction in the Haber Process to make ammonia was exothermic and the backward reaction is therefore endothermic... Please correct me if I'm wrong.

[conzobonzo]

if you were to agitate the solution, would it become colder still?

@Evertonian94 You know where 0 degrees fahrenheit came from. You need to know where Fahrenheit decided to put his 100 degrees to fully understand it. I've heard that he have measured the temperature of his wife for this, who was a bit ill that day. A video on this would be pretty handy. :)
