Inspired by problem 17 from the International Young Naturalists Tournament (2021), this investigation aims to establish a relationship between the speed of sound in air as a function of air temperature at constant pressure and humidity. This goal is achieved by exploiting certain properties of standing sound waves in a tube, sealed off at one end. By varying the length of the tube and the temperature of the air inside, properties of the air, such as its molar mass, can also be determined.<br \/>\n<em>Keywords:<\/em> standing waves; speed of sound; temperature; molar mass; experimental investigation; IYNT<\/p>\n<a href=\"https:\/\/azbuki.bg\/en\/member-login\/\">Log in to read the full text<\/a>","protected":false},"excerpt":{"rendered":"<p>Geo Kalfov First Private Mathematical High School \u2013 Sofia (Bulgaria) https:\/\/doi.org\/10.53656\/nat2022-2.02 Abstract.
