An open pot of water is boiling on a stove at sea level under standard atmospher

Question

An open pot of water is boiling on a stove at sea level under standard atmospheric pressure. Pick the correct answer(s). Note that there is a negative score for picking a wrong answer. as the water is boiling, the heat supplied by the stove causes the temperature of the water to continuously rise the heat supplied from the stove to the water causes the kinetic energy of the water molecules to increase the saturation pressure of the water is standard atmospheric pressure The boiling point of the water can be increased if the surrounding pressure (or ambient pressure) is decreased

Explanation / Answer

ANSWER : OPTION 2

The heat supplied from the stove to the water causes the kinetic energy of the water molecules to increase.

Option 1 is wrong because when the water is boiling initially temperature does not rises as all the heat is utilized to convert the liquid phase into gaseous phase in the form of latent heat of vapourization.

Option 2 ,As the water get heated up then it will be converted into vapour form and the stationary water will have some kinetic energy because it has been converted into vapour(gaseous phase).

Option 3 is wrong because it is not necessary that only standard atmospheric pressure is the saturation pressure,it can be any pressure depending on the situation.

Option 4 is wrong because the boiling temperature of water decreases with decreasing the surrounding pressure.
