If the pressure is kept constant (isobaric), the temperature will be allowed to change. JFIF C The weight of the mass increases the With no mass on the platform, the piston is raised ~4 The change in volume is calculated by multiplying the change in piston height by the piston cross-sectional area. 0000080337 00000 n 0000061229 00000 n 0000082047 00000 n changing their orientation. www.cas.miamioh.edu/~yarrisjm/S02laslab2.pdf. 0000013013 00000 n Open Document.
