Question

Marshall is interested in how temperature affects the volume of a new polymer gel that may be useful in sorting DNA fragments using gel electrophoresis. He conducts an experiment in which he measures the volume of the mass of the gel, in milliliters (mL), at various temperatures, in Kelvin (K). He plots his results, as shown in the graph.

Which of the following is the best explanation of Marshall's results?


Question 3 of 5
A. Temperature is directly proportional to the volume of a given mass.
B. Energy may change form, but it cannot be created nor destroyed.
C. Temperature is

Answer 1

please help!

Answer 2

A. Temperature is directly proportional to the volume of a given mass.
B. Energy may change form, but it cannot be created nor destroyed.
C. Temperature is inversely proportional to the volume of a given mass.
D. Mass may change form, but it can neither be created nor destroyed.

Answer 3

I'd say C because look how depending on the temp the mass will rise (Which it is)

Answer 4

Volume*

Answer 5

thanks.... are you sure though?

Answer 6

OH WAIT
Sorry misread a and c

Answer 7

really...

Answer 8

any other possible answers?

Answer 9

A.
B is the second law of thermodynamics
C means as one decreases the other increases
D is right but doesn't relate to the graph

Answer 10

ok. what would A mean?

Answer 11

A means as one increases so does the other
We have a Temp increasing as vol does

Answer 12

would the answer be, B?

Answer 13

No it's A. B (The second law of thermodynamics is like D, it's right but doesn't relate to the graph)

Answer 14

Oh ok! Thank you so much!

Answer 15

No prob.
