A cooking pan with an inner diameter of 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.

Answer :

The boiling point of a liquid highly depends on the
pressure in the atmosphere. In this case, 101 kPa is the ambient or atmospheric
pressure. At this pressure, water boils at exactly 100 degrees Celsius. Hence
the answer is:



100 degrees Celsius
