Question

What is Boiling..?
Explain.....

Answer 1

✌❤Boiling❤✌

• ✌❤✔When a liquid is heated gradually, at a particular temperature saturated vapour pressure of the liquid becomes equal to atmospheric pressure, now bubbles of vapour rise to the surface d liquid. This process is called boiling of the liquid.✔❤✌

• ✌❤✔The temperature at which a liquid boils, is called boiling point The boiling point of water increases with increase in pre sure decreases with decrease in pressure.✔❤✌

The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure.

▪The normal boiling point is the temperature at which the vapor pressure of the liquid is equal to standard pressure.

▫ Because atmospheric pressure can change based on location, the boiling point of a liquid changes with the external pressure.

▪The normal boiling point is a constant because it is defined relative to the standard atmospheric pressure of 760 mmHg (or 1 atm or 101.3 kPa).

EXTRA INFORMATION:-

▫The temperature required to reach the necessary vapour becomes lower and lower as we get higher above sea level, and the liquid will therefore boil at a lower temperature.

▪Adding any solute to water will increase the boiling temperature, as it reduces the vapour pressure, meaning a slightly higher temperature is required in order for the vapour pressure to become equal to atmospheric pressure and boil the water.

▫Another factor that can affect the boiling temperature of water is the material that the vessel it’s being boiled in is made of.
