Quick Answer: What is boiling point of gas?

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it. The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere (760 torr).

What is meant by boiling point of gas?

The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the surrounding atmospheric pressure, thus facilitating transition of the material between gaseous and liquid phases.

Do gases have a boiling point?

All pure substances that occur in a liquid and a gas state have boiling points. Some substances skip the liquid state and go directly from solid to gas (e.g. carbon dioxide at standard pressure). Some substances decompose before they boil when you heat up the liquid.

What is meant by boiling point?

boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature.

Can you boil gas?

You can boil gasoline; but, if there is an ignition source all the vapor would burn and there could be an explosion that could level and have leveled buildings. Gasoline is made by boiling oil.

What liquid has highest boiling point?

1 Answer

• Ethanol 78.5 ∘C .
• Peanut oil 230 ∘C .
• Glycerol 290.0 ∘C .

Why boiling point is important?

Besides indicating the physical state (liquid or gas) of a substance at ambient or room temperature, boiling point serves as an indicator of volatility even for laymen, with higher boiling points indicating lower volatility. … Knowing the boiling point of a chemical is also very important for its storage & transport.

What is Class 9 boiling point?

Hint: The temperature at which conversion of liquid on heating takes place at standard atmospheric pressure is called the boiling point of that liquid and the phenomenon is called boiling. Complete step by step solution: … Pure water at standard pressure (1atm) boils at 100∘C.
