## Conclusion and Evaluation of the Investigation
### Relationship Tested:
In this investigation, the primary relationship tested was between the amount of gas in a balloon (in terms of inflation) and the volume of the balloon itself, as measured by its diameter. The hypothesis was that increasing the volume of gas injected into the balloon would result in an increase in the balloon’s volume.
### Data and Observations:
From the experimental procedure, diameter measurements of the balloon were recorded under different temperature conditions:
- **Initial inflated state (70°F)**: Diameter = 10 inches
- **After freeze (18°F for 10 min)**: Diameter = 8 inches
- **After hot water bath (100°F for 10 min)**: Diameter = 10.5 inches
The data clearly illustrates that when the balloon was placed in the freezer, the cold temperature caused the gas particles to lose kinetic energy, resulting in a decrease in volume (diameter measurement decreased from 10 inches to 8 inches). Conversely, when the balloon was heated in water, the gas particles gained kinetic energy, causing an expansion and an increase in volume (diameter measurement increased from 10 inches to 10.5 inches).
### Conclusions Drawn:
The data supports the hypothesis that temperature affects the volume of a gas within a confined space, as shown by the changes in the balloon's diameter. This aligns with Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature when pressure is held constant. The experiment demonstrates that an increase in temperature results in an increase in volume, whereas a decrease in temperature results in a decrease in volume.
The relationship observed remained consistent throughout all trials. Each trial produced similar results, affirming that the amount of gas particles—though constant in terms of the initial inflation—was clearly influenced by temperature, challenging the balloon’s ability to maintain a stable volume when external conditions varied.
### Sources of Error:
Potential sources of error in this investigation could include:
1. **Inconsistent Measurements**: The diameter of the balloon could have been measured at different points due to its shape, leading to inconsistent data.
2. **Temperature Fluctuations**: The temperature of the water and the air could have fluctuated, affecting the results.
3. **Balloon Material Variability**: Different balloons may react differently based on the material, leading to variations in elasticity and volume change.
### Suggested Improvements:
If this experiment were to be repeated, several improvements could enhance the reliability of the data collected:
1. **Standardized Measurement Techniques**: Using a caliper for measuring the diameter of the balloon would provide more accurate and repeatable results.
2. **Temperature Control**: Utilize a thermometer to ensure the water bath and the air temperature are consistently controlled, improving the precision of the data collected.
3. **Larger Sample Size**: Increasing the number of trials and using more balloons could improve the overall reliability of the data.
4. **Continuous Monitoring**: Instead of fixed times in hot water or the freezer, continuously monitor the balloon's diameter to capture real-time changes in response to temperature changes.
In summary, the investigation successfully illustrated the relationship between gas volume and temperature, providing insights consistent with fundamental gas laws. Addressing identified sources of error and implementing suggested improvements could yield even more robust results in future iterations of this experiment.
