Cycle C - Practice Set (Ideal Gas Properties)

  • At least a paragraph reflection that describes the types of problems you really understood and why.  Give at least one example.
  • The first problem which asked me to find the mole fraction of neon in the container was seemed a lot easier than I initially thought. I’m also familiar with the concept that volume occupied. I think that it’s safe to say that any problems having to do with partial pressure make a lot of sense to me. Finding molecular masses of different gas samples seemed straightforward and simple.

  • At least a paragraph reflection that describes the types of problems you struggled with and why. Give at least one example.
  • Finding the final pressure of an ideal gas was confusing to me since I didn’t use the approach. Determining different variables from a graph proved to be a bit challenging and a bit harder than I had expected. Overall, I had some trouble determining the numerical figures for my answers since I haven’t experienced too many of those questions. In class, we focused more on simply seeing if the numerical value was going to be greater/smaller rather than actually finding that value. I also forgot when a gas would be at STP.
  • At least one picture of something you did in class during the week with a description of the picture.
  • In this picture, we emptied a tea bag and then folded the bag into a cylinder shape before burning it. In this picture, the bag is in the process of burning.
