A heating-cooling system cycles gases between states. Assume this system is using 1.00 moles of an ideal gas with a C(v) = 25.00 J/mol· K. In this cycle, the gas was cooled from 561.0 K to 392.0 K. In addition, the pressure changed from 20.0 atm to 14.0 atm while the volume remained constant. Calculate AE for this process.

Introduction to chemistry

Chemistry is a branch of science that deals with the analysis of material and the substances that comprise it. It also manages the properties of these substances and their reactions to form new substances. It is basically centered on particles and atoms that make up components and mixtures. These chemical species will in general connect using bonds.
