1. Place a temperature strip (58-88 oF) in a clean, dry pop bottle. Attach a Pressure Pumper . Determine the mass.
Pump the pumper 25 times. Weigh and record mass to the nearest 0.1 gram. Repeat.
At 0, 50, 100, 150, 200 pumps, record the temperature on the temperature strip in the second table.
| Pumps | Mass (g) | Mass Gained |
| 0 | ||
| 25 | ||
| 50 | ||
| 75 | ||
| 100 | ||
| 125 | ||
| 150 | ||
| 175 | ||
| 200 |
| Pumps | Temperature oF | Temperature oC |
| 0 | ||
| 50 | ||
| 100 | ||
| 150 | ||
| 200 | ||
| Release Slowly | What happens to temperature? |
2. Create a chart showing the relationship between mass and air volume. Select the correct chart type and plot data on correct axes. Use back of this sheet.
3. What is the mass of air in one pump?
4. What happens to temperature as pressure is increased. What happens when it is decreased?
5. Create a chart showing the relationship between temperature and pressure.
