SUMMARY

The discussion centers on the concept of interface temperature in thermodynamics, specifically in the context of two metal rods connected at one end with differing temperatures. The interface temperature is defined as the temperature at the junction of the two rods, which must be equal due to thermal contact. To solve for the interface temperature and the rate of heat transfer, relevant equations from heat transfer principles are necessary. Participants suggest consulting resources like HyperPhysics for foundational equations related to heat conduction.

PREREQUISITES
  • Understanding of basic thermodynamics principles
  • Familiarity with heat transfer concepts
  • Knowledge of thermal conductivity and its equations
  • Ability to apply Fourier's law of heat conduction
NEXT STEPS
  • Study Fourier's law of heat conduction for calculating heat transfer rates
  • Learn about thermal equilibrium and its implications in connected systems
  • Explore the concept of thermal resistance in composite materials
  • Consult HyperPhysics for equations related to heat transfer and interface temperature
USEFUL FOR

Students and professionals in physics, particularly those studying thermodynamics and heat transfer, as well as engineers working with thermal systems involving conductive materials.

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
