Change After Boiling

What will be changes occur to the water if we boiled it since systems pressure is equal to atmospheric pressure (till the temperature of water become 10 0 C 100^\circ C ) and then kept it to an hour to cool down and again start to heat it?

It's boiling point will be decreases. There will be no change occur. It's boiling point will be increases. It will not boiled since pressure is constant. It will be vapourized earlier.

Every solution or any substance has its own activation energy which can be change through out some critical,physical and chemical changes. eg.That might be reaction which explain clear about Activation Energy (Ae) water is boiled through heating. you know why its boiled because it has molecular energy, simply the molecules get energy from heat and then it provide to other molecule , so systems tendency to gain and loss energy will be change after some time because of inactive molecule. In case of water after boiling it.again cool and boiled.This process will be occure simultaneously will decreases the activation energy..so water boiling point decreases i.e. it will be < 100°C it never equal to nor increases over 100°C.
