Answer

Brief Explanations:

  • Question 7: Accuracy and precision are independent. A measurement can be accurate without being precise.
  • Question 8: 90 is a definite number within the range of 80 - 100, not a range itself.
  • Question 9: Increasing temperature is heat - transfer (usually), not work in the mechanical sense.
