The discussion revolves around determining the temperature of a substance using its internal energy (U), volume (V), and number of moles (N). Participants explore the relationship between these variables, particularly in the context of ideal gases.
The discussion is active, with participants offering various perspectives on the problem. Some have provided formulas that may be relevant, while others are seeking more context about the specific problem to assist further.
One participant notes that the problem involves ranking temperatures of ideal gases based on different internal energy values, number of molecules, and volumes, indicating a comparative aspect to the question.
I think you will need more than the internal energy, volume and number of moles even if it is an ideal gas. You will need to know an initial state (ie. P,V, n or V, T, n or P, T, n or P, V, T) and the change in internal energy and volume. This is because the heat capacity of a gas is somewhat temperature dependent so although dU = nC_vdT it is not necessarily true that U = nC_vT.synx said:How can I find the temperature of something if I'm give the internal energy(U), volume(V), and number of moles(N). I thought it'd just be pv = nrt but I am not sure what to do with the internal energy or how to use it with pressure. Thanks.
