Homework Help Overview

The discussion revolves around heat transfer between two copper masses of different temperatures, specifically a 10kg mass at 450K and an 8kg mass at 480K. Participants are exploring the principles of heat transfer and the implications of mass and material properties.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the direction of heat transfer, with one suggesting that heat flows from warm to cool objects. There is also inquiry into the significance of mass and material in this context. Additionally, a participant raises questions about the lowest possible temperature and the nature of heat transfer mechanisms, specifically distinguishing between conduction, convection, and radiation.

Discussion Status

The discussion is ongoing, with various interpretations being explored regarding heat transfer principles. Some participants have provided insights into temperature limits and the nature of heat transfer, while others express uncertainty about specific concepts.

Contextual Notes

Participants are navigating assumptions about temperature scales and the fundamental limits of temperature, as well as the mechanisms of heat transfer, which may not be fully understood by all involved.

Homework Statement



A 10kg copper mass at a temperature of 450 degrees K is pushed up against another copper mass of 8kg at a temperature of 480 degrees k. How will the heat be transferred?

I know it won't be transferred from hot to cold.. or would it be? does mass matter and or the material matter?

Heat flows from warm objects to cooler objects.
 
I have another question.
 
I don't think it will, but I don't fully understand your other question.
 
Question 2

The lowest temp. is?

0 degrees C

-273 degrees F

0 degrees K

32 degrees K

-100 degrees K

The internet tells me that 0 degrees celsius is the coldest and that 0 Kelvin is too...
 
One cannot get to or below 0 Kelvins, but as far as I know, that's the only actual limit the Universe imposes on temperature.
 
When heat is transferred by passing vibrations from one atom to another, it is called conduction or radiation? I know it's def. not convection.

Thank you
 
or is it convection?
