Who, in the 1860s, undertook a thorough investigation of the gas laws expressing the relationships of pressure, temperature, and volume in carbon dioxide? 

Key Points

• Thomas Andrews was an Irish chemist who made significant contributions to the study of gases.
• In the 1860s, Andrews conducted a series of experiments on carbon dioxide gas and discovered the critical temperature and pressure of the gas.
• He also formulated the concept of the critical point, which is the temperature and pressure at which a gas and liquid are indistinguishable.
• Andrews' work on the gas laws of carbon dioxide was an important step towards understanding the behavior of gases in general.

Additional Information

• Giulio Natta was an Italian chemist who won the Nobel Prize in Chemistry in 1963 for his work on high polymers.
• John Dalton was an English chemist who developed the atomic theory of matter and made important contributions to the study of gases.
• Marguerite Perey was a French physicist who discovered the element francium.
