Volatility (chemistry) Volatility (chemistry) In chemistry and physics, volatility is quantified by the tendency of a substance to vaporize. Volatility is directly related to a substance's vapor pressure. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure. The term is primarily written to be applied to liquids; however, it may be used to describe the process of sublimation which is associated with solid substances, such as dry ice (solid carbon dioxide) and osmium tetroxide (OsO), which can change directly from the solid state to a vapor, without becoming liquid.

Tendency of the rate of profit to fall form of production since in the end the profit principle itself would suffer a breakdown. However, because Marx never published any finished manuscript on the TRPF himself, because the tendency is hard to prove or disprove theoretically and because it is hard to test and measure the rate of profit, Marx's TRPF theory has been a topic of global controversy for more than a century. In Adam Smith's TRPF theory, the falling tendency resulted from increased competition which accompanied the growth of capital. Intensifying competition itself would drive down the average profit rate. Criticizing Adam Smith, David Ricardo argued that
