what is the purpose of the condenser? question 3 options: a) to de-superheat the entering vapor, condense the vapor to a liquid,
Alona [7]

Option (a) is correct,

the purpose of the condenser is to de-superheat, the entering vapor, condense the vapor to a liquid, and subcool the liquid.

<h3>What is a condenser's purpose?</h3>

A condenser uses a cooling fluid to attempt to sufficiently cool down a vapor, changing its state from a vapor to a liquid. Condensers come in a variety of designs, including direct condensing, which involves coming into direct touch with the cooling fluid and the vapor.

<h3>What kind of vapor is condensed?</h3>

The vapour that needs to condense might be highly different and can even include non-condensable vapour, such as air, which greatly affects how well the condenser works.

One gram-mole of methyl chloride vapor is contained in a vessel at 100°C and 10atm.(a) Use the ideal-gas equation of state to es
777dan777 [17]

Answer:

a) The volume of the system is 3.062 Liters.

b) Percentage error results from assuming ideal-gas behavior is 9.36%.

Explanation:

a)

Using ideal gas equation:

PV = nRT

where,

P = Pressure of gas = 10 atm

V = Volume of gas = ?

n = number of moles of gas = 1 mol

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 100°C = 100+273K=373 K

Putting values in above equation, we get:

(10 atm)\times V=1 mol\times (0.0821L.atm/mol.K)\times 373 K

V=\frac{1 mol\times (0.0821L.atm/mol.K)\times 373 K}{10 atm}

V = 3.062 L

The volume of the system is 3.062 Liters.

b)

Volume of the container = V' = 2.8 L

System volume = V = 3.062 L

Percentage error of volume:

To calculate the percentage error, we use the equation:

\%\text{ error}=\frac{|\text{Experimental value - Accepted value}|}{\text{Accepted value}}\times 100

=\frac{|3.062L-2.8 L|}{2.8 L}\times 100=9.36\%

Percentage error results from assuming ideal-gas behavior is 9.36%.
