Apiece of plastic (sample q), was heated at a constant rate. after 20 minutes of adding heat, the plastic melted. when an identical piece of plastic (sample r), was heated with twice as much heat per minute, the plastic melted in 10 minutes. how do the melting points of the two pieces of plastic compare?
a. the melting point of sample r is double that of sample q.
b. the melting points of sample q and sample r are the same.
c. the melting point of sample r is slightly higher than sample q's.
d. the melting point of sample q is higher than sample r's.

The correct answer is option B which is the melting points of sample Q and sample R are the same.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
