Read the passage below and answer the question that follows.

In August 1856, American scientist Eunice Newton Foote presented her groundbreaking findings on atmospheric gas absorption at the annual meeting of the American Association for the Advancement of Science in Albany, New York. Foote had constructed an experimental apparatus consisting of two glass cylinders, each fitted with a thermometer, into which she introduced different gases—including compressed air, rarefied air, hydrogen, and carbon dioxide. After placing the filled cylinders in direct sunlight, Foote recorded the resulting temperature changes over several hours. She observed that the cylinder filled with moist carbon dioxide trapped significantly more heat than the cylinder containing dry atmospheric air, and took much longer to cool down once removed from sunlight.

In her paper, titled 'Circumstances Affecting the Heat of the Sun's Rays,' Foote explicitly deduced that an atmosphere composed of carbon dioxide would impart to our Earth a higher temperature than it currently possessed. Although Foote was a member of the association, her paper was read aloud by Joseph Henry, the first secretary of the Smithsonian Institution, because women were not permitted to formally present research at the conference. Following the presentation, an abstract of Foote’s paper was published in November 1856 in the American Journal of Science and Arts. Despite this publication, her experimental proof of carbon dioxide's heat-trapping properties remained largely unacknowledged by mainstream European physicists for over a century.

Based on the passage, place the following events regarding Eunice Foote's experiment and its presentation in the correct chronological order in which they occurred, from earliest to latest.

  1. 1Foote introduced distinct gases into two glass cylinders fitted with thermometers.
  2. 2Foote positioned the gas-filled cylinders in direct sunlight to track temperature changes.
  3. 3Joseph Henry read Foote's paper aloud at the AAAS meeting in Albany.
  4. 4An abstract of Foote's research paper appeared in the American Journal of Science and Arts.

Answer

The correct chronological sequence of events is: first, Foote introduced different gases into two glass cylinders; second, she exposed the filled cylinders to direct sunlight to record temperature changes; third, Joseph Henry read her paper aloud at the August 1856 meeting in Albany; fourth, an abstract of the paper was published in November 1856.
The passage lays out an explicit chronological sequence: Foote first introduced different gases into the thermometer-equipped cylinders, then placed those filled cylinders into direct sunlight to record temperatures. Next, Joseph Henry read her paper aloud at the August 1856 AAAS meeting, and finally, an abstract was published in November 1856 in the American Journal of Science and Arts.

Step-by-Step Solution

1
Locate the description of how the experiment was set up.
The text states that Foote first constructed an apparatus of two glass cylinders and introduced different gases into them.
Preparing the cylinders with gases was the baseline task before testing could occur.
2
Trace the subsequent step in the experimental procedure.
After filling the cylinders, Foote placed them in direct sunlight to record temperature changes over several hours.
Sunlight exposure was necessary to measure how each gas absorbed heat.
3
Identify the event surrounding the presentation of the research.
The text states that Joseph Henry read Foote's paper aloud at the AAAS meeting in Albany in August 1856.
The paper was presented at the conference after the experimental data had been gathered.
4
Find the final event mentioned in the chronological sequence.
An abstract of Foote's paper was published in November 1856 in the American Journal of Science and Arts.
The journal publication occurred months after the August presentation.
