When water boils, why does its temperature remain constant?

We write the relation for Boyle's law in the form, PV=K_B when the temperature remains constant. In this relation, the magnitude of K_B depends upon the

When a piece of ice is placed in water at room temperatur, ice melts and water cools down. Why does their temperture change?

Change in heat energy of the object when its temperature is changed:

When sound waves travel from air to glass, which of these remain constant?

What do a ferromagnetic material when its temperature increases aboveCurie temperature?

If a given mass of gas occupies a volume 60 m^3 one atmospheric pressure and temperature of 100^@C , what will be its volume at 4 atmospheric pressure when temperature remains same?

Boiling point of water is defined as the temperature at which:

Assertion : If there is no external torque on a body about its centre of mass, then the velocity of the centre of mass remains constant. Reason : The linear momentum of an isolated system remains constant.
