The scientist Benjamin Thompson observed that heat was generated when a moving drill contacted a piece of metal. How can Thompson's observation be explained by the Kinetic Theory of Matter? @e.mccormick

Question

e.mccormick · Answer

OK, have you looked at the Kinetic Theory of Matter?

anonymous · Answer

yes

e.mccormick · Answer

OK, what does it say about collisions and energy?  Heat flow?

anonymous · Answer

In my booklet, it has a part on Thompson and his work, and it talks about in 1798 he observed that intense heat was produced when pieces of brass were drilled...

e.mccormick · Answer

Yes.  The friction of the bit and the sheet causes heat.  But you need to look at how that relates to the Kinetic Theory of Matter.

the drilling motion?

e.mccormick · Answer

Did you look at what the Kinetic Theory says about collisions and energy?  How this is related to heat flow?

anonymous · Answer

it says the energy of moving particles is called heat.

e.mccormick · Answer

Good.  So, if you have a nice, tightly packed bunch of particles called a drill bit and you spin them, that has some more motion involved.  Then you have that motion pressed into a plate of metal, causing more collisions where the two meet.  What happens then?

i got stuck...

e.mccormick · Answer

On?  With?
