Question

during their experiment, nolan and hunter simultaneously pour hot water in the tank on the left and cold water in the tank on the right. then, they seal the tops of the cylinders and allow the water in the tanks to intermingle through the glass tube.
to determine if heat is transferred, nolan wants to place his hands in each tank of water at the beginning and end of the experiment. hunter wants to use a thermometer to measure the temperature in each tank at the beginning and end of the experiment.
how do nolan and hunter’s proposed methods compare?
a. neither nolan or hunter could collect meaningful data using their proposed methods.
b. nolan’s method would allow him to make a descriptive observation. hunter’s method would allow him to include numbers in his data
c. nolan’s method would require the use of a different apparatus. hunter’s method would work better if a spring scale was used instead of a thermometer
d. nolan’s method would produce more precise and accurate data than hunter’s method

Explanation:

Nolan's method (using hands) gives a descriptive observation (like feeling hot/cold), while Hunter's method (using a thermometer) provides quantitative data (numerical temperature values). Option A is wrong as Hunter’s method can collect meaningful data. Option C is wrong because a spring scale measures force, not temperature. Option D is wrong as a thermometer is more precise/accurate than hand - based sensing. So the correct option is B.

Answer:

B. Nolan's method would allow him to make a descriptive observation. Hunter's method would allow him to include numbers in his data
