Abstract

        The purpose ofthis sludy is to design, fabricalion and evatuatc ofgasses expdsion coeflicient appararus. The fabdcated model should have IOC €ftciency value. Research methodology is to fnd the Basses expansion coeftcient by isobaric and isochoric process and compare wjlh theorelical value. tt were founil rhai ne Basses expansion coefficient by isobaric and isochoric pfocess are 0.00351 .Cr and 0.00346 .C' which have erors of 4.1 and 5.46 percent from standard value respeclively. The resulr of rhis erp€rimenr accord w'th Charls and cay- Lussac Law. Experts evaluation on IOC is 0.87 which higher than 0.6.
