and take multiple measurements tn average them out.

make ur object totally dry before you start next measurement.

sorry if wrong

Explanation:

Precise volumes must always be measured at constant temperature because, due to thermal expansion, changes in temperature are followed by changes in volume. For example water at 10 °C has much smaller volume than at 80 °C. Volumetric vessels are usually calibrated for 20 °C (25 °C in the USA).

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.
