Relating the Temperature and Volume of a Gas

Document Content and Description Below

Comparing Temperature and Volume The temperature and volume of a gas are closely related. In this task, you’ll observe how changing the air temperature inside an empty water bottle aàects its vol... ume. To do this, you’ll immerse the water bottle in hot water and cold water and compare the volume of hot air to the volume of cold air inside the bottle. Estimated time to complete: 2 hours If you’ve purchased an Edmentum lab kit, remove the thermometer and graduated cylinder from the bag labeled Common Materials. These materials are italicized in the following equipment list. Then gather any additional items shown in the list. If you’re not using an Edmentum lab kit, alternatives are suggested in parentheses. You’ll need these materials: thermometer, readable from 0°C to 100°C (32°F to 212°F) graduated cylinder (may also use kitchen measures: cup, tablespoon, teaspoon, ½ teaspoon) disposable plastic water bottle with cap (10-ounce capacity preferred), or similar transparent bottle with a tight-Õtting cap two large bowls or pots, large enough to completely contain the water bottle hot and cold tap water ice stopwatch (may also use a timer or a clock) Stay safe! Be careful when handling hot water to avoid burns. Part A Write a hypothesis about what will happen to the air in the plastic bottle when its temperature is decreased. What relationship do you expect to Õnd between temperature and volume?4/11/2021 Task: Comparing Temperature and Volume https://f1.app.edmentum.com/courseware-delivery/ua/48778863/45422831/aHR0cHM6Ly9mMS5hcHAuZWRtZW50dW0uY29tL2xlYXJuZXItdWkvdX… 2/12 Answer: I think the temperature and volume will either lead to a decrease or an increase in pressure. Characters used: 93 / 15000 Part B It’s time to get started. Fill the plastic bottle to the brim with water. Then pour the water into a graduated cylinder or other measuring tool to measure the total capacity of the bottle. Note that you may need to Õll the measuring tool multiple times. To recall how to use a graduated cylinder, watch this video on measuring volume before continuing. If you are using household measuring tools, use these conversions to record the exact capacity of the bottle in milliliters (mL). Visit the math review for help with converting units: 1 cup = 240 mL 1 tablespoon = 15 mL 1 teaspoon = 5 mL What is the capacity of the bottle in milliliters? [Show More]
