Homework Answers
If work done by the system on the surroundings. Then system lost some energy, so internal energy of the gas inside the piston decreases. So change in internal energy delta E = negative value.
Change in enthalpy of the coffee = -(amount of energy lost by coffee)
= - 50 kJ
If there is no work in the process then delta H = delta E
That means in isochoric process (at constant volume)

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
