An expertly designed format for arranging, processing, accessing, and storing data is called a data structure.
Data structures come in both simple and complex forms, all of which are made to organize data for a certain use. Users find it simple to access the data they need and use it appropriately thanks to data structures. The organizing of information is framed by data structures in a way that both machines and people can better grasp. A data structure may be chosen or created in computer science and computer programming to store data in order to be used with different methods. In some circumstances, the design of the data structure and the algorithm's fundamental operations are closely related. Each data structure comprises information about the data values, relationships between the data and — in some situations — functions that can be applied to the data. For instance, in an object-oriented programming language, the data structure and its related methods are tied together as part of a class description. Although they may be designed to operate with the data structure in non-object oriented languages, these functions are not considered to be a part of the data structure.

Answer:
![Activation\ Energy=2.5\times 10^{-19}\ J](https://tex.z-dn.net/?f=Activation%5C%20Energy%3D2.5%5Ctimes%2010%5E%7B-19%7D%5C%20J)
Explanation:
Using the expression shown below as:
![N_v=N\times e^{-\frac {Q_v}{k\times T}](https://tex.z-dn.net/?f=N_v%3DN%5Ctimes%20e%5E%7B-%5Cfrac%20%7BQ_v%7D%7Bk%5Ctimes%20T%7D)
Where,
is the number of vacancies
N is the number of defective sites
k is Boltzmann's constant = ![1.38\times 10^{-23}\ J/K](https://tex.z-dn.net/?f=1.38%5Ctimes%2010%5E%7B-23%7D%5C%20J%2FK)
is the activation energy
T is the temperature
Given that:
![N_v=2.3\times 10^{13}](https://tex.z-dn.net/?f=N_v%3D2.3%5Ctimes%2010%5E%7B13%7D)
N = 10 moles
1 mole = ![6.023\times 10^{23}](https://tex.z-dn.net/?f=6.023%5Ctimes%2010%5E%7B23%7D)
So,
N = ![10\times 6.023\times 10^{23}=6.023\times 10^{24}](https://tex.z-dn.net/?f=10%5Ctimes%206.023%5Ctimes%2010%5E%7B23%7D%3D6.023%5Ctimes%2010%5E%7B24%7D)
Temperature = 425°C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (425 + 273.15) K = 698.15 K
T = 698.15 K
Applying the values as:
![2.3\times 10^{13}=6.023\times 10^{24}\times e^{-\frac {Q_v}{1.38\times 10^{-23}\times 698.15}](https://tex.z-dn.net/?f=2.3%5Ctimes%2010%5E%7B13%7D%3D6.023%5Ctimes%2010%5E%7B24%7D%5Ctimes%20e%5E%7B-%5Cfrac%20%7BQ_v%7D%7B1.38%5Ctimes%2010%5E%7B-23%7D%5Ctimes%20698.15%7D)
![ln[\frac {2.3}{6.023}\times 10^{-11}]=-\frac {Q_v}{1.38\times 10^{-23}\times 698.15}](https://tex.z-dn.net/?f=ln%5B%5Cfrac%20%7B2.3%7D%7B6.023%7D%5Ctimes%2010%5E%7B-11%7D%5D%3D-%5Cfrac%20%7BQ_v%7D%7B1.38%5Ctimes%2010%5E%7B-23%7D%5Ctimes%20698.15%7D)
![Q_v=2.5\times 10^{-19}\ J](https://tex.z-dn.net/?f=Q_v%3D2.5%5Ctimes%2010%5E%7B-19%7D%5C%20J)
Answer:
275 Kelvin
Explanation:
Coefficient of Performance=11
![T_H=\text {Absolute Temperature of high temperature reservoir=300 K}](https://tex.z-dn.net/?f=T_H%3D%5Ctext%20%7BAbsolute%20Temperature%20of%20high%20temperature%20reservoir%3D300%20K%7D)

![\text {Coefficient of performance for carnot cooler}\\=\frac {T_L}{T_H-T_L}\\\Rightarrow 11=\frac{T_L}{300-T_L}\\\Rightarrow 11(300-T_L)=T_L\\\Rightarrow 3300-11T_L=T_L\\\Rightarrow 3300=T_L+11T_L\\\Rightarrow 3300=12T_L\\\Rightarrow T_L=\frac {3300}{12}\\\Rightarrow T_L=275\ K\\\Therefore \text{Temperature at which the refrigerator absorbs heat=275 Kelvin}](https://tex.z-dn.net/?f=%5Ctext%20%7BCoefficient%20of%20performance%20for%20carnot%20cooler%7D%5C%5C%3D%5Cfrac%20%7BT_L%7D%7BT_H-T_L%7D%5C%5C%5CRightarrow%2011%3D%5Cfrac%7BT_L%7D%7B300-T_L%7D%5C%5C%5CRightarrow%2011%28300-T_L%29%3DT_L%5C%5C%5CRightarrow%203300-11T_L%3DT_L%5C%5C%5CRightarrow%203300%3DT_L%2B11T_L%5C%5C%5CRightarrow%203300%3D12T_L%5C%5C%5CRightarrow%20T_L%3D%5Cfrac%20%7B3300%7D%7B12%7D%5C%5C%5CRightarrow%20T_L%3D275%5C%20K%5C%5C%5CTherefore%20%5Ctext%7BTemperature%20at%20which%20the%20refrigerator%20absorbs%20heat%3D275%20Kelvin%7D)
