Determining of there is Change

[Jessica Helfond 2F]

Will we be told is there is changed/constant volume or temperature? Or is it something we will have to figure out using PV=nRT?

[Aria Soeprono 2F]

Sometimes it will tell you, but sometimes you have to assume based on definitions alone. For example, by definition of enthalpy, you would expect the pressure to remain the same.

It's probably a safer bet to know how to utilize PV=nRT to see if there is a change in pressure/volume/temperature, as that's what we did in one of the example questions in class yesterday. Essentially, just start marking off each aspect of the formula that remains constant in the reaction/situation given. If there's a change on one side of the equation, there must be a change on the opposing side to ensure that the equation is balanced.
