In this lab experience, students examine the amount of work a system is capable of doing. A syringe is attached to a flask where a chemical reaction takes place. As the gas builds up in the syringe the plunger rises and is capable of lifting a surprising amount of weight. This lab does not include VR.
Safety:Before conducting the lab, review the safety precautions on the student page with the class. Discuss any safety precautions that are specific to your science laboratory or classroom.
