Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The temperature at which a substance changes states from a liquid to a gas.
A
freezing point
B
boiling point
C
melting point
D
None of the above
Explanation: 

Detailed explanation-1: -The temperature at which the liquid changes into the gaseous state is known as the boiling point. Boiling point can be defined as the liquid boiling at 100 degrees of centigrade.

Detailed explanation-2: -The boiling point of a pure substance is the temperature at which the substance transitions from a liquid to the gaseous phase. At this point, the vapor pressure of the liquid is equal to the applied pressure on the liquid. The boiling point at a pressure of 1 atmosphere is called the normal boiling point.

Detailed explanation-3: -The boiling point of a substance is the temperature at which it changes from a liquid to a gas (boiling) or vice versa from a gas to a liquid (condensing).

Detailed explanation-4: -This temperature is called the boiling point. Once the liquid starts to boil, the temperature remains constant until all of the liquid has been converted to a gas. The normal boiling point of water is 100oC.
