[Q]: The Soave equation adds an acentric factor to this statement, and the virial equation measures deviations from this law using a compressibility factor. This law derived by Benoit Clapeyron can account for density in its "dirty mop" form, and when A and B terms are added to account for the volume and interactions between particles, it is called van der Waals equation. Containing a namesake constant that is Boltzmann's constant times Avogadro's number is, for 10 points, what law usually stated as PV equals nRT
[A]: Science

[Q]: Materials with this property can exhibit a noise arising from self-organized criticality known as the Barkhausen effect. The Ising model was originally formulated to study this phenomenon, in which regions become separated by Bloch walls and materials exhibiting this property are frequently subject to hysteretic effects. The anti variety of this property disappears above the Neel point, while this property itself disappears above the Curie point, where the material transitions to paramagnetism. FTP, identify this form of magnetism resulting from the spontaneous alignment of domains, which is present in metals such as nickel and iron.

[Q]: One of his early works was a case study of the war bond loan appeal made by Kate Smith. His theories of deviance are summed up in a chart that plots Cultural goals against Institutionalised means, with rebellion defined as new goals and new means. One of his better known theories was built upon by Robert Agnew and regards the relationship between social structures and crime. He discussed the process by which the developers of a process or idea are forgotten, obliteration by incorporation, and in his most famous work contrasts "middle range" theories with grand theories. He also discussed positive feedback loops based on expectations, which this thinker called the self-fulfilling prophecy. For 10 points name this sociologist who also coined the term "role mode," developed Strain Theory, and wrote Social Theory and Social Structure.
