[#386] The ratio of the mass of water vapour in a given volume (parcel) of air to the mass of the remaining dry air describes the:
Correct Answer
(B) Mixing ratio
Explanation
Solution: The ratio of the mass of water vapour in a given volume (parcel) of air to the mass of the remaining dry air describes the mixing ratio.
[#387] If the sun suddenly began emitting more energy, the earth's radiative equilibrium temperature would:
Correct Answer
(A) Increase
Explanation
Solution: If the sun suddenly began emitting more energy, the earth's radiative equilibrium temperature would increase.
[#388] If the average temperature of the sun increased, the wavelength of peak solar emission would:
Correct Answer
(A) Shift to a shorter wavelength
Explanation
Solution: If the average temperature of the sun increased, the wavelength of peak solar emission would decrease.
[#389] When the air temperature increases, the saturation vapour pressure will:
Correct Answer
(A) Increase
Explanation
Solution: At higher temperatures, the kinetic energy of water vapour molecules increases, so increasing the pressure
[#390] As the air temperature increases, the air's capacity for water vapour:
Correct Answer
(A) Increases
Explanation
Solution: The air's capacity for water vapour increases as air temperature increases. Air with a temperature of 30°C can hold more than three times as much water vapour as air at 10°C. Relative humidity varies significantly when the temperature changes, even when the actual amount of water vapour in the air remains the same.
