Explanation:

A 0.5-m3 rigid tank contains refrigerant-134a initially at 200 kPa and 40 percent quality. Heat is transferred now to the refrigerant from a source at 358C until the pressure rises to 400 kPa. Determine (a) the entropy change of the refrigerant, (b) the entropy change of the heat source, and (c) the total entropy change for this process.

Answers

Answer:

(a) $\Delta S_(ref)=3.876(kJ)/(K)$

(b) $S_(heat\ source)=-1.678(kJ)/(K)$

Explanation:

Hello,

(a) In this case, such refrigerant, we can notice that at the given conditions, the initial entropy from property tables (Cengel 7th ed) is:

$s_(initial)=s_f+xs_(fg)=0.15457+0.4*0.78316=0.4678(kJ)/(kg*K)$

Now, for the final condition, we first need to compute the initial specific volume as it remains the same (rigid tank) after the thermodynamic process:

$v_(initial)=v_f+xv_(fg)=0.0007533+0.4*(0.099867-0.0007533)=0.0404(m^3)/(kg)$

Then, at 400 kPa we evaluate the given volume that is also between the liquid and vapor specific volume, thus, we calculate the quality at the end of the process:

$x_f=(0.0404-0.0007907)/(0.051201-0.0007907) =0.786$

With it, we compute the final entropy:

$s_(final)=0.24761+0.785*0.67929=0.781(kJ)/(kg*K)$

Finally, entropy change for the refrigerant turns out:

$m_(ref)=(0.5m^3)/(0.0404(m^3)/(kg) )=12.4kg \n\n\Delta S_(ref)=12.4kg *(0.781(kJ)/(kg*K)-0.4678(kJ)/(kg*K) )\n\n\Delta S_(ref)=3.876(kJ)/(K)$

(b) In this case, by using the first law of thermodynamics we compute the acquired heat by the refrigerant from the heat source by computing the initial and final internal energy respectively (no work is done):

$Q=\Delta U$

$u_(initial)=38.28+0.4*186.21=112.764(kJ)/(kg)\n \nu_(final)=63.62+0.786*171.45=198.40(kJ)/(kg)$

Hence:

$Q=12.4kg*(198.40-112.764)(kJ)/(kg) =1059.1kJ$

Finally, the entropy change of the heat source (which release the heat, therefore it is negative):

$S_(heat\ source)=(1059.1kJ )/((358+273.15)K) \n\nS_(heat\ source)=-1.678(kJ)/(K)$

$\Delta S _(tot)=3.876(kJ)/(K)-1.678(kJ)/(K)\n\n\Delta S _(tot)=2.198(kJ)/(K)$

Which has thermodynamic agreement as it is positive

Regards.

Final answer:

The entropy changes in this process can be partially calculated using principles from thermodynamics. However, without the exact heat transfer, not all values can be determined.

Explanation:

The calculation of the entropy change in this thermodynamic process involves principles from thermodynamics and requires steps to determine the initial and final states of the refrigerant. First, we would need to find the entropy at the initial and final states using the refrigerant properties table for refrigerant-134a and the provided information (200 kPa and 40% quality initially, 400 kPa finally). The entropy change of the refrigerant is the difference between the final and initial entropy.

Next, the entropy change of the heat source is calculated as the heat transfer divided by the absolute temperature of the source. However, the problem does not provide the amount of heat transferred from the source, making it impossible to determine this value directly.

Finally, in an isolated system, the total entropy change of the process is the sum of the entropy changes of the refrigerant and the heat source. Here, the precise values cannot be calculated due to a lack of specific data including exact heat transfer.

Inside a calorimeter, two solutions are mixed and result in an endothermic reaction. Which of the following best illustrates how this reaction affects the water in the calorimeter? (2 points)Select one:
a. The reaction has no effect on the water. The kinetic energy of the water molecules remains the same.
b. The reaction causes the temperature of the water to increase. The kinetic energy of the water molecules increases.
c. The reaction causes the temperature of the water to decrease. The kinetic energy of the water molecules decreases.
d. The reaction causes the temperature of the water to decrease. Then, the water gains heat from the surroundings and the kinetic energy of the water molecules increases.

Answers

The correct option is C. A calorimeter is an isolated system. In isolated systems there is no exchange whatsoever with the surrounding. In an isolated system, an endothermic reaction results in a decrease in the temperature of the system. This is in contrast to the effect of an endothermic reaction in an open system. The heat of reaction remains a positive quantity.

A gummie bear was tested through a flame-calorimeter test. the bear had a mass of 1.850 grams and the temperature of 100.0 milliliters of water increased by 15.0 degrees celsius. how many calories were in the gummie bear? show all of your calculations.

Answers

Answer:- 1500 calories

Solution:- mass of bear = 1.850 g

volume of water = 100.0 mL

Density of water is 1.00 g/moL. So, mass of water would be 100.0 g.

delta T for water = 15.0 degree C

specific heat capacity for water is 1 cal/(g* degree C)

q = m x c x delta T

where, q is the heat energy, m is mass, c is specific heat capacity and delta T is change in temperature.

for water, q = 100.0 x 1 x 15.0

q = 1500 calorie

heat gained by water = heat lost by bear

So, the 1.850 g bear has 1500 cal or 1.50 Cal.

(Where, 1 Cal = 1000 cal)
