Heat Transfer in Copper Masses: 10kg/450K & 8kg/480K

[Justhelp]

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?

 

[Whovian]

Heat flows from warm objects to cooler objects.

I have another question.

 

[Whovian]

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...

 

[Whovian]

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

 

[Justhelp]

or is it convection?
