Answer:  Assuming 25 is 25C, 54.9C

Explanation:  The specific heat of zinc is 0.388 J/gC.  With 195 grams, we see that for the whole tray, the temperature will change by 1 C for every 75.66J, since (0.388J/gC)*(195g) = 75.66 J/C.

Thus, (2260J)/(75.66J/C) = 29.9 C increase.  Add that to 25 to yield 54.9 C (or K, if the 25 was in Kelvin).

B. The chemical reaction with nerves, which is slower than other sensory processes

C. Attractive forces between the air and vinegar molecules

D. Random collisions between the air and vinegar molecules.

<span>The answer is D. While the particles may be moving at high velocities even at room temperatures, the delay is due to the numerous collisions between the vinegar molecules and the air molecules.This changes the vinegar’s molecules directions from straight lines to random unpredictable paths</span>
