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 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
