Question 1

What happens to percentage uncertainty when you square a value?

  • It decreases
  • It remains the same
  • It doubles

💡 Hint: Remember the percentage uncertainty formula.

Question 2

True or False: The absolute uncertainty decreases when a measurement is multiplied by a number.

  • True
  • False

💡 Hint: Consider how uncertainties scale with multiplication.

Challenge Problems

Push your limits with challenges.

Question 1

A cylinder's height is measured as 10.0 ± 0.5 cm and the diameter as 4.0 ± 0.1 cm. Calculate the volume and the percentage uncertainty in that volume.

💡 Hint: Don’t forget that the height contributes to the final uncertainty along with the diameter.

Question 2

A temperature of 25 ± 0.5 °C affects the volume directly measured as 1.5 L ± 0.02 L. Calculate the volume at this temperature while considering the uncertainties.

💡 Hint: Always account for how temperature fluctuations impact measurements in conjunction with uncertainties!
