A1.00 kPa
B10.0 kPa
C1000 kPa
D100 kPa
Answer & Solution
Correct answer: D. 100 kPa
1. Write down both conversion factors: 1 bar = 100,000 Pa and 1 kPa = 1000 Pa.
2. Convert the bar reading to pascals: 1 bar gives 100,000 Pa.
3. Divide by 1000 Pa per kPa: 100,000 / 1000 = 100 kPa.
4. Answering 1000 kPa means multiplying by 1000 instead of dividing, which is the usual slip here.
