A cooking pan whose inner diameter is 20 cm is filled with water and covered with a 4-kg lid. If the local atmospheric pressure is 101 kPa, determine the temperature at which the water starts boiling when it is heated.
Added by Consuelo T.
Step 1
The pressure inside the pan is equal to the atmospheric pressure plus the pressure due to the weight of the lid. The pressure due to the weight of the lid can be calculated using the formula: Pressure = Force/Area The force is equal to the weight of the lid, Show more…

A cooking pan whose inner diameter is $20 \mathrm{cm}$ is filled with water and covered with a 4-kg lid. If the local atmospheric pressure is $101 \mathrm{kPa}$, determine the temperature at which the water starts boiling when it is heated.
A cook puts 8.80 g of water in a 2.00-L pressure cooker that is then warmed to 510°C. What is the pressure inside the container? (Assume room temperature is 20°C.)
