R-134a is contained in a frictionless piston-cylinder device. The initial temperaure of the mixture is 39.37 oC. Over an hour 40
Komok [63]

Solution :

Given :

Initial temperature of the refrigerant is :

$T_i=39.37 ^ \circ C$

   = ( 39.37 + 273 ) K

  = 312.3 K

Room which is maintained at constant temperature is :

$T_o=22 ^ \circ C$

    = (22+273) K

    = 295 K

The thermal energy transferred to the room is :

Q = 400 kJ

   = $400 \times 10^3 \ J$

Therefore, the total entropy generation during the thermal energy process is :

$\Delta S =\left[\frac{-Q}{T_i}+ \frac{+Q}{T_i}\right]$

Here, -Q = heat is leaving the system maintained at a temperature of $T_i$ K.

 +Q = heat is entering the system maintained at a temperature of $T_o$ K.    

Therefore, substituting the values :

$\Delta S =\left[\frac{-400\times 10^3}{312.3}+ \frac{400\times 10^3}{295}\right]$

      = [-1280.8197 + 1355.9322]

      = 75.1125 J/K

       = 0.0751125 kJ/K

      = 0.075 kJ/K

5. What is the final "Celsius" temperature if 2.40 L of gas at 30.5 C is cooled until the volume reaches 1.00 L at constant pres
slega [8]

Answer:

Final temperature of the gas = -146.63 °C

Explanation:

At constant pressure, volume and temperature of the gases are related as:

\frac{V_1}{T_1}=\frac{V_2}{T_2}

Where,

V1 = Initial volume = 1.00 L

V2 = Final volume = 2.40 L

T1 = Initial temperature = 30.5 °C = 30.5 + 273.15 = 303.65 K

Now, substitute the values in the above equation,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

\frac{2.40\;L}{303.65}=\frac{1.00\;L}{T_2}

T_2=\frac{1.00\times 303.65}{2.40}

T2 = 126.52 K

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

T( °C) = T(K) - 273.15

          = 126.52 - 273.15 = -146.63 °C
