4. ### What are (a) Tf and (b) pf?

A. Tf/Ti = 1; that's the definition of isothermal. B. PV/T = constant. With T constant, PV = constant ==> Pf/Pi = Vi/Vf = 1/3.

5. ### A 12,000-pF capacitor holds 28.0 x 10-8 C of charge. What is the voltage across the capacitor?

If C is 12000 pF, Q is 28 x 10 -8 C 12000 pF = 1.2 x 10-8 F U = Q / C = (28 / 1.2) x 10-8 = 2.33 V I think.

9. ### The capacitance of a portion of a circuit is to be reduced from 4800 pF to 2900 pF. What capacitance can be...?

added? you remove 1900 pF to reduce 4800 to 2900 pF if they are in parallel. if the 4800 pF is in series with an unknown C to produce 2900 pF, then C = 4800*2900/(4800–2900) = 7300 pF idiotic question, sorry .
