Water that is gaseous rather than liquid is known as water vapour. Evaporation or sublimation are two processes that can be used to create it. Unlike clouds, fog, or mist, which are only suspended drops of liquid water in the atmosphere, water vapour is a gas and cannot be seen.

In the atmosphere, water vapor frequently exists below the boiling point. Boiling water causes the water to evaporate significantly more quickly and produce steam. Since water is boiling, steam frequently contains water droplets. This is known as wet steam because both water droplets and water vapor are present (also called wet vapor).

Answer:

average kinetic energy

Explanation:

When more moles of gas are introduced into a rigid container the deviation from ideal behavior decreases.

According to ideal gas equation,

pV=nRT

n = number of moles of gas

P = pressure of the gas

V = volume of the gas

R = gas constant

T = temperature

Then,  

pV/nRT = 1

Therefore, compressibility factor is,

Z = pV/nRT = 1

For an ideal gas Z = 1 and for real gas, Z may be either greater than one or less than one.

From the equation of deviation from ideal gas behavior it is clear that,

n ∝ 1 / Z

Hence, When more moles of gas are introduced into a rigid container the deviation from ideal behavior decreases.

To prepare a 1.72 m solution of nano3, the volume (in liters) which would you have to dilute 31.9 ml of 3.45 m NaNO3 is 63.9 ml.

This problem can be solved by using the concept of molarity.

Molarity is defined as the ratio of moles of solute to the volume of solution.

Mathematically,

Molarity = moles of solute / volume of solution

Given,

Concentration of NaNO3 = 3.45 m

Volume of NaNO3 = 31.9 ml

As we know that,

Concentration = mole / volume

By substituting all the values, we get

3.45 m = mole / 31.9

Mole = 3.45 × 31.9

Moles of NaNO3 = 110.05 mol

Moles of NaNO3 = 110.05 mol

Molarity of NaNO3 = 1.72 m

By substituting all the values, we get

1.72 m = 110.05 / volume

Volume = 110.05 / 1.72 = 63.9 ml

Thus, we concluded that to prepare a 1.72 m solution of nano3, the volume (in liters) which would you have to dilute 31.9 ml of 3.45 m NaNO3 is 63.9 ml.

The heat required to raise the temperature of a 16.8 g block of silver from 600°C to its melting point, 961.8°C, can be calculated using the equation:  

Q₁ = mcΔT  

where Q is the heat required (in joules), m is the mass of the silver (in grams), c is the specific heat of silver (in joules per gram per degree Celsius), and ΔT is the change in temperature (in degrees Celsius).  

The heat required would be:  

Q₁ = (16.8 g)(0.240 J/g°C)(961.8°C - 600°C)  

Q₁ = 158,608 J  

The heat required to fully melt the sample at this temperature can be calculated using the equation:  

Q₂ = mΔHf  

where Q is the heat required (in joules), m is the mass of the silver (in grams), and ΔHf is the heat of fusion of silver (in joules per gram).  The heat required would be:  

Q₂ = (16.8 g)(88 J/g)  

Q₂ = 1,472 J
