The pressure inside an aerosol can is 3.80 atm at 25.0°C. If the temperature is increased from 25.0°C to 100.0°C, what would be
ladessa [460]

Answer:

B. 4.76 atm

Explanation:

P_1 = Initial pressure = 3.8 atm

T_1 = Initial temperature = 25+273.15\ \text{K}

P_2 = Final pressure

T_2 = Final temperature = 100+273.15\ \text{K}

From Gay Lussac's law we have

\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=P_1\dfrac{T_2}{T_1}\\\Rightarrow P_2=3.8\times\dfrac{100+273.15}{25+273.15}\\\Rightarrow P_2=4.76\ \text{atm}

The pressure inside the can would be 4.76\ \text{atm}.

Relative humidity is described as: Group of answer choices a basically unused concept when it comes to weather topics. the amoun
Bad White [126]

Correct answer:

The relative humidity is best described as the amount of water vapor in the air at a given temperature expressed as a percentage of the water vapor capacity of the air.

What is relative humidity?

The ratio of the current absolute humidity to the highest absolute humidity is known as relative humidity (which depends on the current air temperature).

Water vapor is also measured by relative humidity, which is stated as a percentage but RELATIVE to the air's temperature. In other words, it is a comparison between the amount of water vapor that is actually present in the air and the maximum amount of vapor that is possible for the air at the current temperature.

With the same quantity of absolute/specific humidity, air will have a HIGHER relative humidity if it is cooler and a LOWER relative humidity if it is warmer because warm air may contain more water vapor (moisture) than cold air. The actual amount of moisture (absolute humidity) in the air is what we "feel" outside.

Effects of a thunderstorm in order
Ede4ka [16]

Answer:

Rainfall from thunderstorms causes flash flooding, killing more people each year than hurricanes, tornadoes or lightning. Lightning is responsible for many fires around the world each year, and cause fatalities. Hail up to the size of softballs damages cars and windows, and kills wildlife caught out in the open.

A sample of 325 mg of neon occupies 2 dm^3 at 20.0 c. use the perfect gas law to determine the pressure of the gas.
Musya8 [376]

Answer:

0.1935atm is the pressure of the gas.

Explanation:

In the problem you have the mass of Neon (You can obtain moles using molar mass), you have volume, and temperature. You can use general ideal gas law to solve pressure:

PV = nRT

P = nRT / V

<em>Where P is pressure in atm, n are moles, R is gas constant (0.082atmL/molK), T is absolute temperature (20.0°C + 273.15 = 293.15K), and V is volume in L = Volume in dm³</em>

<em />

<em>Moles gas:</em>

Molar mass Ne = 20.1797g/mol

0.325g * (1mol / 20.1797g) = 0.0161 moles

Replacing:

P = nRT / V

P = 0.0161 moles * 0.082atmL/molK * 293.15K / 2L

P = 0.1935atm is the pressure of the gas
