The image shows the example of finding the number of vacancies in 1 cubic meter of copper (Cu) at 1000 degrees celcius (1273 k) considering the image data.

Replicating the problem in the image, calculate the number of vacancies but at room temperature.
Explain why there is such a difference in the number of vacancies at both temperatures.

Para 1 m3:
N = NA (Pcu/Acu) x 1 m³ = 8 X 1028 sitios
Nv = N exp (-Qv/KT) = 8 X 1028 exp (-0.9/8.62X10-5 X 1273)
Nv = 2.19 X 1025 sitios

Problem 2: Helium is a very important element for both industrial and research applications. In its gas form it can be used for welding, and since it has a very low melting point (only 0.95 K under 2.5 MPa) it can be used in liquid form to cool superconducting magnets, such as those found in particle physics experiments. Say we have a cylinder of n = 145 moles of Helium gas at room temperature (T = 20° C). The cylinder has a radius of r = 17.5 cm and a height h = 1.45 m. Part (a) What pressure (in kPa) is the helium gas under? P = ______ Part (b) Helium is usually kept in the highest pressure gas cylinders, which can typically withstand at least 500 atm of pressure. Would the tank in part (a) be able to maintain its structural integrity? Part (c) In principle, these tanks could fail if the temperature of the Helium started rising - if they were stored in a hot environment, for instance. To determine how much of a danger this is, calculate the temperature (in C) the Helium gas…

An ideal gas is confined within a thermally isolated cylinder. It consists of N atoms initially at a pressure of p0. A movable piston seals the right end of the cylinder, as shown in the figure. (Figure 1)A given amount of heat Q is slowly added to the gas, while the piston allows the gas to expand in such a way that the gas's temperature remains constant at T0. A) As heat is added, the pressure in this gas __________. increases decreases remains constant cannot be determined B) Is the internal energy of the gas the same before and after Q is added? yes no C) Does the second law of thermodynamics forbid converting all of the absorbed heat Q into work done by the piston? yes no D) The (Kelvin-Planck statement of the) second law of thermodynamics reads as follows:It is impossible for an engine working in a cycle to produce no other effect than that of extracting heat from a reservoir and performing an equivalent amount of work.The phrase "in a…

Suppose you have 0.53 moles of an ideal gas. What is the average kinetic energy of that gas (in units of kJ) if the temperature of the gas is 280.2K? Note: It is understood that the unit of your answer is some number of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
