Gen Chem Destroyer #41
Started by topdent1
This question is difficult for me to explain because their wording is poor...they never tell you if the system or surrounding temperature decreases...in this question i am assuming they are talking about the surroundings, so if the surround temperature decreases that means the system took in energy (in the form of heat) and therefore an increase in temperature of the system leads to a decrease in temperature of the surroundings...conversely a decrease in temperature of the system and an increase in temperature of the surroundings is accompanied by an exothermic reaction..
AGAIN im not sure if they are taking about the system or surroundings, i think this question is poor
Thanks Osims.
I was also wondering about gen chem number 59. The formula P(MW)=DRT. Destroyer says that because we are changing the molecular weight, the density will change. This make sense because we can clearly see from the equation that they are proportional. My question is, wouldn't temp. change also because it is also proportional to MW?
