WebJun 25, 2024 · Cp always exceeds Cv by an amount n R [ n is moles of gas and R is the universal gas constant. Therefore Cp-Cv tells you the amount of expansion work that takes place when a gas is heated. Cp/Cv ... WebA time horizon of 100 years is used by regulators (e.g., the California Air Resources Board). CARB maintains a list of GWPs for some common refrigerants. For more information, please visit the IPCC website. The most common refrigerant today, R-22, has a 100-year GWP of 1,810, almost 2,000 times the potency of carbon dioxide, so just one pound ...
