For specific heat and measuring 5 mL of air within a syringe and comparing while submerging in boiling water and ice water and extrapolating back, is your measurement of absolute zero close to the actual value (-273 °C)? How might you change the experiment to get closer to the actual value?
We cannot help you answer questions about a lab experiment you supposedly performed while we didn't.

To determine if the measurement of absolute zero using specific heat and a syringe is close to the actual value of -273 °C, you would need to compare your measurement to the known value. However, without the specific measurements from your experiment, it's difficult to give a definitive answer.
To improve the accuracy of your experiment and get closer to the actual value of absolute zero, you can consider the following modifications:
1. Calibration: Make sure the syringe and thermometer used in the experiment are properly calibrated. This ensures that the measurements are accurate and reliable.
2. Increase precision: Increase the precision of your measurements by using more precise instruments, such as a digital thermometer, instead of analog ones. This can help reduce measurement errors and improve accuracy.
3. Multiple trials: Perform multiple trials of the experiment to obtain an average value. This helps to mitigate any random errors and provides a more reliable result.
4. Use a larger sample size: Instead of using only 5 mL of air, consider increasing the volume. A larger sample size provides more accurate measurements and reduces the impact of any errors in the measurements.
5. Improve temperature control: Ensure that the water baths used for submerging the syringe in boiling water and ice water are precisely controlled. This can be achieved by using a temperature-controlled water bath or a more accurate temperature-measuring device.
By implementing these modifications, you can improve the accuracy and reliability of your experiment, potentially getting you closer to the actual value of absolute zero (-273 °C).
