A small weight put on a pressure cooker increases the pressure of steam because
It is air tight
Incorrect AnswerArea of contact is very small
Incorrect AnswerDensity of metal is very high
Incorrect AnswerPressure builds up irrespective of the weight placed
Correct AnswerExplanation:
Pressure builds up irrespective of the weight placed
-Water vaporizes into steam, increasing the pressure inside the cooker as it heats. Because the boiling point of water depends on pressure, it rises too, just enough to keep the water and steam temperature hovering around the boiling point for the higher pressure.
