To find CP/CV of a gas, one sometimes uses the following method. A certain amount of gas with initial temperature T0, pressure P0, and volume V0 is heated by a current through a platinum wire for a time t. The experiment is done twice: first with a constant volume V0 with pressure changing from P0 to P1, and then at a constant pressure P0 with the volume changing from V0 to V1. The time t is the same in both experiments. Find the ratio CP/CV. The gas may be considered ideal.

Basic Chemical Calculations (Process and Variables)

A basic chemical calculation involves the application of the law of chemical proportions to various reactions and material and energy balance calculations on various chemical processes. Basic chemical calculation helps students analyze various chemical processes and develop problem-solving skills. The chemical manufacturing processes are divided into unit operations involving physical changes of material and unit processes involving the chemical transformation of materials. For instance, fluid flow, heat transfer, and mass transfer are unit operations, and oxidation, reduction, and pyrolysis are unit processes.
