A gas with initial conditions p_i, V_i, and T_i expands isothermally until V_ f=6 V_i.

What are (a) T_f and (b) p_f? in terms of T_f/T_i and P_f/P_i

First I dont understand what this is saying at all. And Second I need to know how to solve it.

(a) If the gas expands isothermally, that means T is constant, so Tf = Ti

(b) When T = constant,

p*V = constant

Therefore

pi*Vi = pf*Vf = 6 pf*Vi

pf = pi/6
