Q. What is the greatest possible error for a measurement of 4 liters?____ liters
Determine Precision: Determine the precision for the measurement of 4 liters.Since the measurement is given as a whole number without any decimal or fractional parts, we can assume that the precision is to the nearest liter.Precision: 1 liter
Calculate Error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision.Greatest possible error =2Precision=21 liter=0.5 liters
