The boiling point of the water depends only on the absolute pressure p. the atmospheric temperature is given by P=101000 pa and the pressure from the lid we calculate by dividing its weight with the surface area of lid. the weight is product of mass and the gravitational acceleration. surface area is calculated by given diameter.
The absolute pressure p is sum of atmospheric pressure and the pressure from the weight of lid.
At this pressure the boiling temperature of water is 100.2.
