Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The cooling of liquid foods held in plates, bowls, or cups is an event encountered several times a day. Here, it is reported a simple practical activity that demonstrates the role played by different heat transfer mechanisms in that process. The experiments can be done even at home with basic kitchenware. The demonstrations show the important role of evaporative cooling in many cases, versus convection and radiation. In this work, the applicability of Newton’s law of cooling is verified, the contributions of the different heat transfer mechanisms are quantified, and values of heat transfer coefficients are estimated. However, the data analyses and the discussions of the results can be adjusted to different audiences.
