1.5 kg of argon (m=39.94) at 1.025 bar and 30°c in a closed system is compressed reversibly and adiabatically according to the law pv=constant until the pressure is 4.10 bar. calculate (i) the initial and final volumes (ii)the final temperature (iii) the workdone

d.7.5cm is your answer

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
