Simplify each of the following Boolean expressions as much as possible using identities:

XY + (1 ⊕ X) + XZ + XY + XZ ABC + ABCD + ABD
BC + ABCD + ABCD + ABCD

(X + Y)(XY) + ZXY + XZY (A + B ) (A + B) ( AB)

(A + AB) ((A + B + C) (C) ((A + B) x z+ xyz + x y
y z + x y z + xz + y

(A + AB) (A + B) + B
(X + Y) + (X ⊕ ( X ⊕ XY))

(X⊕(XY⊕(X⊕X)))

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
