Homework Help Overview

The discussion revolves around the concept of interface temperature in thermodynamics, specifically in the context of two metal rods connected at one end with different temperatures at their free ends. The original poster expresses confusion about the definition of interface temperature and seeks guidance on how to approach the problem of finding this temperature and the rate of heat transfer through the rods.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the nature of the problem as one involving heat conductivity and the requirement that the temperatures at the joint of the rods must be equal. The original poster seeks foundational understanding and relevant equations, indicating a lack of resources and knowledge in thermodynamics.

Discussion Status

The conversation is ongoing, with some participants providing clarifications about the problem's nature and suggesting resources for further study. However, there is no explicit consensus on the methods to solve the problem or the specific equations needed.

Contextual Notes

The original poster mentions a lack of appropriate textbooks and resources, which may limit their ability to engage with the problem effectively. There is also an indication of uncertainty regarding the fundamental concepts of heat transfer.

I have come across a problem involving an interface temperature and I have no idea what an interface temperature even is although I'm guessing it's the temperature at the joining of two objects

The question has two metal rods connected together at one end, the other ends are kept at a and b degrees kelvin, assuming the rods are insulated to the outside world find the interface temperature and find the rate that the heat travels through the rods

I have no idea where to start here, I don't even have any books to consult. The physics books I do have are lifgarbagez mechanics which has nothing to do with beginner thermodynamics and stowe's introduction to statistical mechanics which talks about the partition function but nothing like this. I'm also pretty sure those books are at a higher level than this so...

If someone could give me a little nudge in the right direction, that'd be great!

This is a heat conductivity problem. The question is simply asking for the temperature of either rod at the joint. The joined ends of each rod will necessarily be at the same temperature since they are in thermal contact with each other.

Could you possibly link me to some relevant equations on this?
I really have no idea what I'm supposed to be trying to do here

I understand that the temperature should be the same at the ends of each rod but I don't know how to find what that temperature should be, nor how I could find the rate the heat travels through the rods from this

Are you studying heat transfer? Do you have a textbook? Try: http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/heatra.html
