Picture waiting hours for a meal to be done. During the Renaissance era this was the daily struggle of people around the world. This common problem turned into a solution when Denis Papin invented the pressure cooker in 1679. Without this invention, cooking a meal would take more time and effort to prepare, we would lack understanding for the use of the pressure cooker, and hospital steam sterilizers wouldn't have been inspired.
During the Renaissance the pressure cooker was an item that was cherished. Before the pressure cooker was invented people cooked using fire. According to Yona Williams from the article Facts About Living in the 1500s: Household and food," At the start of each morning, a fire was lit and items were added to the pot throughout the day. The ingredients usually created a stew that continuously simmered to make dinner for a family." Which would require the cook to keep an observation on the food cooking. With the pressure cooker, there was no worry of the food simmering over due to the safety valve. …show more content…
A pressure cooker is a sealed pot with a safety valve that controls the steam pressure inside. Once the pot is heated up, it makes the liquid inside form steam, which raises the pressure in the pot. This high pressure steam has two major effects: it raises the boiling point of water in the pot and the pressure, forcing liquid into the food. This device uses the first and second laws of thermodynamics. It uses the first law because the first law states,"Energy can neither be created nor destroyed. It can only change forms. In any process, the total energy of the universe remains the same. For a thermodynamic cycle the net heat supplied to the system equals the net work done by the system." This project uses thermodynamics because more energy isn't created, the energy is just transformed from liquid to
