Answer:

RH = 20%

Explanation:

Data given:

water pressure at 0°C  = 4.85 g/m³

Actual water vapor density = 0.97 g/m³

Relative humidity (RH) = ?

Solution:

Formula used

       Relative humidity (RH) =  \frac{actual vapor density}{saturated vapor density of water}  x 100%

As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.

So,

put values in the above formula

     Relative humidity (RH) =  0.97 g/m³ /  4.85 g/m³ x 100%

     Relative humidity (RH) =  0.2 x 100%

     Relative humidity (RH) = 20%

So,  

Relative humidity (RH) = 20%

What is the force of attraction between the particles in a salt crystal
Papessa [141]

Answer:

Electrostatic attraction between the ions

Step-by-step explanation:

A salt crystal consists of Na⁺ and Cl⁻ ions stacked together in a crystal.

The ions have opposite charges, so they are electrostatically attracted to each other.

Because the ions are so close together, the attractive forces are quite large.

g Of the following substances, only ________ has London dispersion forces as its only intermolecular force. Of the following sub
kati45 [8]

Answer:

CCl4

Explanation:

Let us look at the structure of CCl4 closely in order to really determine if it is the correct answer to the question or not.

While it is true that the electro negativity of carbon is 2.5 and that of chlorine is 3.0, hence an electro negativity difference of 0.5 exists between carbon and chlorine leading to the presence of four polar covalent bonds in the carbon tetrachloride molecule. We must also observe that the molecule, carbon tetrachloride, has a tetrahedral molecular geometry. This implies that the four dipoles in the molecule are symmetrical and cancel out each other hence the molecule is non polar. Being a non polar molecule, only London forces are expected to be present as an intermolecular force, hence the answer.

A sample of gas in a closed container at a temperature of 100oC and 3 atm is heated to 300oC. What is the pressure of the gas at
Goshia [24]

Answer:

6.14 atm

Explanation:

Initial temperature (T₁) = 100 °C

Initial pressure (P₁) = 4 atm

Final temperature (T₂) = 300 °C

Final pressure (P₂) =?

NOTE: Volume = constant (since the system is a closed system)

Next, we shall convert celsius temperature to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

Initial temperature (T₁) = 100 °C

Initial temperature (T₁) = 100 °C + 273 = 373 K

Final temperature (T₂) = 300 °C

Final temperature (T₂) = 300 °C + 273 = 573 K

Finally, we shall determine the pressure at the highest temperature as follow:

Initial temperature (T₁) = 373 K

Initial pressure (P₁) = 4 atm

Final temperature (T₂) = 573 K

Final pressure (P₂) =?

P₁ / T₁ = P₂ / T₂

4 / 373 = P₂ / 573

Cross multiply

373 × P₂ = 4 × 573

373 × P₂ = 2292

Divide both side by 373

P₂ = 2292 / 373

P₂ = 6.14 atm

Thus, the pressure at the highest temperature is 6.14 atm
