4 grams of a saturated liquid are converted to a saturated vapor by being heated in a weighted piston–cylinder device arranged t
o maintain the pressure at 200 kPa. During the phase conversion, the volume of the system increases by 1000 cm3, 5 kJ of heat are required, and the temperature of the substance stays constant at 80°C. Estimate the sfg of the substance when its temperature is 80°C.

Answer:
Estimated number of indigenous faults remaining undetected is 6
Explanation:
The maximum likelihood estimate of indigenous faults is given by,
here,
= the number of unseeded faults = 6
= number of seeded faults = 30
= number of seeded faults found = 15
So NF will be calculated as,
And the estimate of faults remaining is = 12 - 6 = 6
