Thermodynamic experiments on gases with a computer on-line

Abstract

Experiments on the adiabatic expansion of air are presented. Historical problems in the measurement of specific heats of gases are overcome using a fast acquisition on-line technique for gas thermometry. Pressure oscillations are seen to arise from non-steady-state heat inputs, and temperature corrections are evaluated. Education applications to the teaching of thermodynamics are discussed.

Recent advances in classroom physics

“…The availability of classroom management software [264][265][266], homework delivery services [267][268][269][270][271][272][273], computer-based laboratory tools , electronic student response systems [296-297], simulation software [64, [298][299][300][301][302][303][304], instructional software [305][306][307][308][309][310][311][312][313][314][315][316][317][318][319][320][321][322][323], computing software [323][324][325][326][327][328][329] and access to the Internet [330][331][332][333][334][335]…”

“…These can be used in class, as part of homework or simply as an additional tool available for students to learn physics concepts. Some of the software more commonly used in physics classes is listed in [305][306][307][308][309][310][311][312][313][314][315][316][317][318][319][320][321][322][323].…”

“…For example, a textbook may include a CD-ROM or instructors may purchase access to a homework delivery service [267][268][269][270][271][272][273], for their students. There is a wealth of computer software available that has been designed to help students learn physics and solve physics problems [305][306][307][308][309][310][311][312][313][314][315][316][317][318][319][320][321][322], some of which has been designed to accompany particular texts. There are also non-computer-based supplemental materials (e.g.…”
