Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 25.0 cm in diameter and the gauge pressure inside is 300 atm? Neglect the weight of the lid.

Step-by-step solution Step 1 of 7 Product of pressure and area is numerically equals the magnitude of force acting on that area. Apply this concept to find the required result. Step 2 of 7 The equation to find the pressure is, …… (1) Here, is pressure, is force applied and is area perpendicular to the force. Step 3 of 7 Radius circular lid is, Therefore, Step 4 of 7 Area of the lid is, Here, is radius.
