Define and distinguish between relative humidity and specific humidity
What will be an ideal response?
Both are measures of the amount of water vapor in the atmosphere. Relative humidity is the ratio between the amount of water vapor in the air to the maximum water vapor possible in the air at the given temperature. It is expressed as a percentage. Relative humidity varies because of water vapor or temperature changes in the air. Specific humidity is a measure of the mass of water vapor (g) per mass of air (kg). Because specific humidity is a mass, it is not affected by changes in temperature and pressure. The maximum mass of water vapor possible in a kg of air at a specified temperature is the maximum specific humidity. To convert from specific humidity to relative humidity, divide the specific humidity by the maximum specific humidity and multiply by 100.
