A certain amount of heat was added to a piece of plastic (sample Q), and the plastic melted after 20 minutes. The same amount of heat was added twice as fast to an identical piece of plastic (sample R), and the plastic melted in 10 minutes. How do the melting points of the two pieces of plastic compare?
