Biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet. We have used the biological processes of microorganisms for more than 6,000 years to make useful food products, such as bread and cheese, and to preserve dairy products. According to the Biotechnology Industry Organization, “Modern biotechnology provides breakthrough products and technologies to combat […]

A thick piston is initially held in a cylinder by a pin as shown in Fig.1.39. Assume that the cylinder contains carbon dioxide at 220 kPa and take ambient temperature as 300 K. The density of the piston is 8000 kg/m3. Assume atmospheric pressure as 100 kPa. If the pin is removed then the piston will move up. Assume that after a while the gas […]
