Rounding off to 2 decimal places, then

v=10.36 m/s

A 1-kilogram parcel of air is at 35°c and contains 7 grams of water vapor. What is the relative humidity?
Nitella [24]

Answer:

20%

Explanation:

Relative Humidity (%) = (water vapor content÷water vapor capacity) × 100

=(7÷35)×100

=(0.2)×100

=20%

According to the Temperature-Water Vapor Capacity Table, the water capacity at 35 °C is 35 grams.

Water Vapor Capacity: The amount of water (grams) which air can hold at a given temperature.

Water Vapor Content: The amount of water vapor actually present in the air.
