The property which primarily controls how much water can be present as a gas is:
Assoli18 [71]
The temperature of the air is the property which primarily controls how much water can be present as a gas. 

Meteorology is the study of the atmosphere. It primarily focuses on weather which is defined as the condition of the atmosphere at a certain time and place. It changes every day depending on earth location. There are five factors that affect weather namely, temperature, pressure, humidity, wind and precipitation.

The question above primarily talks about humidity-the amount of water vapor in the air. As the  temperature increases, the air or gas can hold more water. The warmer the air is, the more water it can possibly hold as vapor.

Power is the rate at which energy is?
Mrrafil [7]
In physics, power is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.

a 0.1 kg slinky sits at the top of a staircase with 14 J of potential energy. How high is the staircase?
Bezzdna [24]

Answer: The staircase is 14.28 m high.

Explanation:

Given : Mass = 0.1 kg

Potential energy = 14 J

Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.

P.E = mgh

where,

m = mass

g = gravitational energy = 9.8 m/s^{2}

h = height of object

Substitute the values into above formula as follows.

P.E = m \times g \times h\\14 J = 0.1 kg \times 9.8 m/s^{2} \times h\\h = \frac{14 J}{0.1 kg \times 9.8 m/s^{2}}\\= \frac{14 J}{0.98 m kg/s^{2}}\\= 14.28 Js^{2}/ mkg          (1 J s^{2}/m kg = 1 m)\\= 14.28 m

Thus, we can conclude that the staircase is 14.28 m high.
