Even though there are several limitations, the ideal gas law serves as a good approximation when attempting to approximate the behavior of gases under various conditions.
News You Can Use
- The ideal gas law is known as
- A pressure cooker is a device that cooks food while not allowing liquid or air to escape during the cooking process. The food is heated at a faster rate because the internal pressure from the boiling liquid causes a much higher temperature water vapor to transfer heat in the system. Because less liquid is needed compared to most conventional cooking methods, pressure cookers allow food to be cooked faster.
- Since most modern pressure cookers have safety release valves that release some of the pressure at pre-determined values, the temperature of the system can be monitored by using the idea gas law as an approximation.
