|
| 1. | Air
molecules can only push, they cannot pull.
|
|
| 2. | The
balloon was sucked into the bottle.
|
|
| 3. | We
boiled water in the flask only to keep the flask from breaking.
|
|
| 4. | The
volume of a gas is INVERSELY related to its temperature.
|
|
| 5. | As
the water inside the flask boils, water vapor forces most of the room air molecules out of the
flask.
|
|
| 6. | When
the flask is removed from the heat and begins to cool, water vapor condenses back into water, thus
creating a high pressure environment.
|
|
| 7. | The
volume of a gas is DIRECTLY related to its temperature.
|
|
| 8. | Bicycle tires might burst if pumped up to a high pressure and then left out in the hot
sun.
|
|
| 9. | When
the balloon is attached to the cooling flask, low pressure sucks the balloon inside the
flask.
|
|
| 10. | The
greater the temperature, the lower the volume of a gas.
|
|
| 11. | When
cooled, gases contract in volume.
|
|
| 12. | The
lower the temperature the greater the volume of a gas.
|
|
| 13. | The
balloon inflated because hot air rises.
|
|
| 14. | The
balloon inflated because gases expand when they are heated.
|
|
| 15. | Boiling water created water vapor which takes up 6600 times more volume than
water.
|
|
| 16. | Other
liquids such as tea, lemonade, or apple juice would NOT have worked just as well in this lab in place
of the water we put in the bottom of the flask because they are fundamentally different from
water.
|
|
| 17. | When
heated, gases expand in volume.
