Marshmallow Lab

Sabrina Gournaris Period 3 troop 27, 2012 Marshmallow The Snack That Acts Like A Gas Objective Record and keep an eye on marshmallow and compare it to Boyles law. Materials -2 mini marshmallows -1 syringe -A pen Experimental occasion 1. Take out marshmallow. 2. Draw face on marshmallow. 3. Open stopcock. 4. braid plunger out. 5. Put marhmallow in syringe. 6. Put plunger back off into syringe. 7. release button plunger so its barely touching the marshmallow. 8.Pull plunger back and record observations. 9. Remove marshmallow and replace it with the second marshmallow. 10. Close stopcock and push plunger so its barely touching the marshmallow again. 11. Record observations. data Table Trial Open Closed 1 (without marshmallow) goose egg, Easy to push. Nothing happened. 2 Nothing, Easy to push. Marshmallow got bigger. 3 Nothing, Easy to push. Marshmallow got bigger. 4 Nothing, Easy to push. Marshmallow got bigger. 5 Nothing, Easy to push. Marshmallow got bigger. Observ ationsEvery time you push with the marshmallow in the tube, the air internal the marshmallow is released. The marshmallow decreases in size. Conclusion Boyles law states that for a fixed measurement a gas at a fixed temperature volume is icy to its wardrobe. The air in the marshmallow is what follows Boyles law. The marshmallow is similar to a gas because when the pressure in the syringe is decreased the pressure in the marshmallow is increased. The volume increases in the marshmallow. So basically when the plunger is pulled out the pressure in the syringe decreases and the volume of the marshmallow increases.
