Problem 46P

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.

Step by step solution Step 1 of 3The boiling point of water depends only on the absolute pressure, .The atmospheric pressure, given is 101kPa.We can calculate the pressure from the lid, by dividing the weight of the lid, with thesurface area of the lid, . is the product of mass and gravitational force,Here mass,
