define boiling point and humidity (2 marks question)
Answers
Explanation:
Boiling point is the temperature at which a liquid boils and turns to vapour.
or
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.
Humidity is the amount of water vapor in the air. If there is a lot of water vapor in the air, the humidity will be high. ... Relative humidity is the amount of water vapor actually in the air, expressed as a percentage of the maximum amount of water vapor the air can hold at the same temperature
