An ideal monatomic gas initially has temperature Ti and pressure pi. It is to expand from volume Vi to volume Vf. (Use any variable or symbol stated above as necessary.)
(a) If the expansion is isothermal, what are the final pressure and the work done by the gas?
Pf=
W=
(b) If, instead, the expansion is adiabatic, what are the final pressure and the work done by the gas?
A loop of diameter 15 cm is placed in a uniform electric field of magnitude 6.0 102 N/C. (a) What is the electric flux through the loop when the electric field is perpendicular to the plane of the loop? N·m2/C.
