- W3204746618 abstract "The purpose of this study is to give middle and high school students work concept through experiments for helping them understand typical stages of operation of a real heat engine by using PASCO's heat engine cycle experiment tools. In order to understand the work of heat engine, isothermal processes, isobaric process, this experiment was carried out with 2 factors; mass and temperature of water, respectively.The change in pressure is measured with a low pressure sensor. The change in piston height is measured by the attached string over rotary motion sensor pulley. The change in volume is calculated by multiplying the change in piston height by the piston cross-sectional area.The main results of this study are as follows: First, the more the mass increased the more the work of heat engine increased.Second, this operating Heat engine work was increased by increasing the temperature of water.Third, This operating heat engine cycle helps middle and high school students understand typical stages of operation of a real heat engine.Fourth, A difference between heat engine work and the theoretical work was increased by increasing the mass of being added to the cylinder." @default.
