Help me design an expermiment!?
I have a sample of Potassium Nitrate/Sucrose Propellant. It is currently in granular powder form, but can easily be converted into a solid mold. I want to perform a series of experiments to determine its enthalpy of combustion. I figure it will probably involve some sort of calorimetry, but I'm not really sure where to go from there. Any help would be appreciated!

2 AnswersAdd-ons5 years agoFirst time PC builder needing help with installing an OS.?
I'm about to order the components to the desktop I plan on building next month. Every computer/laptop I've had in the past has come preloaded with Windows. I have been satisfied with its performance as an OS, but in the interest of saving money (and just to try something new), I'd like to install a Linux/GNU OS. I'm wondering which distro to install: I've heard Ubuntu is good and easy for beginners. So, if I have a brand new PC, how do I go about installing it?
