Answer:

a ) I= 1.635-i0.0021 b) ∅=   -0.074

Explanation:

a) reactive impeadance= 2πfL

                                 =2(3.14)(147)(0.158)

                                 =145.86 Ω

Z= 171+j145.86

I=V/Z

I=278/(171+j145.86)

I= 1.635-i0.0021

b) ∅=inv.tan (-0.0021/1.635)

 ∅=-0.074

Calculate the amount of heat (in kJ) required to convert 97.6 g of water to steam at 100° C. (The molar heat of vaporization of
Ratling [72]

Answer:

221.17 kJ

Explanation: Note the heat of vaporization is in kJ/mol,then to determine the number of moles of water: divide the mass by 18. Then multiply the number of moles by the molar heat of vaporization of water.

N = 97.6 ÷ 18

Q=molar heat *moles

Q = (40.79) * (97.6 ÷ 18)

This is approximately 221.17 kJ
