Tempurature Transfer

  1. Jun 21, 2012 #1
    1. The problem statement, all variables and given/known data

    A 10kg copper mass at a tempurature of 450 degrees K is pushed up against another copper mass of 8kg at a tempurature 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 transfered 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?
