number 3. For part d I'm finding the work by looking at the area under the graph, and a friend of mine used 1.5kdT, which also seems to make sense in this situation, but we're getting 2 different answers. For the change in internal energy and the heat taken in i know that all i need to do is find one of them and the other one comes easily but I have no idea how to find either one.
