LabВ #14: В Boyle'sВ LawВ

Objective: В В ToВ determineВ theВ relationshipВ betweenВ theВ pressureВ andВ volumeВ ofВ aВ gasВ atВ constantВ temperature. В

Introduction: В В

TheВ relationshipВ ofВ pressureВ toВ volumeВ forВ aВ gasВ inВ aВ rigidВ containerВ wasВ firstВ describedВ in В 1662 В by В theВ IrishВ­bornВ scientistВ SirВ RobertВ BoyleВ (1627В­1691), В andВ isВ knownВ asВ Boyle'sВ Law. В AsВ longВ asВ theВ temperatureВ ofВ theВ gasВ remainsВ constant, В theВ pressureВ ofВ aВ gasВ hasВ aВ predictableВ relationshipВ withВ theВ volumeВ ofВ theВ gas. В

TheВ pressureВ ofВ aВ gasВ isВ aВ measureВ ofВ theВ forceВ theВ gasВ exertsВ onВ theВ wallsВ ofВ the В box. В RecallВ thatВ theВ particlesВ (atomsВ orВ molecules)В ofВ theВ gasВ areВ inВ constantВ motion, В collidingВ withВ eachВ otherВ andВ withВ theВ wallsВ ofВ theirВ container. В TheВ netВ effectВ ofВ theseВ collisionsВ isВ pressure. В EvenВ ifВ aВ gasВ isВ notВ included, В theВ forceВ ofВ collisions В resultsВ inВ pressure. В ForВ example, В theВ airВ aroundВ usВ exertsВ aВ forceВ onВ everyВ objectВ itВ touches, В andВ weВ canВ measureВ thisВ atmosphericВ pressureВ withВ aВ barometer. В

InВ thisВ activity, В youВ willВ useВ aВ dataloggerВ (calledВ aВ SPARK) В andВ aВ PressureВ SensorВ connectedВ toВ aВ syringeВ fullВ ofВ airВ toВ investigateВ theВ relationshipВ betweenВ theВ volumeВ andВ pressureВ ofВ aВ gas. В

Treatment: В

PartВ A. В В MeasuringВ AirВ PressureВ

FollowВ PARTВ AВ ofВ theВ SPARKВ directionsВ inВ orderВ toВ determineВ theВ pressureВ ofВ airВ inВ theВ roomВ inВ fourВ differentВ unitsВ (kilopascals, В atmospheres, В millimetersВ ofВ Hg, В andВ torr). В RecordВ yourВ resultsВ inВ yourВ labВ notebook. В В

PartВ B. В В Boyle'sВ LawВ

FollowВ PartВ BВ ofВ theВ SPARKВ directionsВ inВ orderВ toВ obtainВ theВ pressureВ asВ theВ volumeВ ofВ airВ isВ changedВ fromВ 60В toВ 20В millilitersВ inВ 5В mLВ increments. В В RecordВ yourВ results. В
