Module 2 Assiagnment

Can you pleae solve this and show all your work

4 ) Every temperature measuring instrument makes use of specific physical property in order to measure temperature objectively . Which physical properties are used in thermocouple , PT sensors and mercury - in - glass thermometer ? Briefly describe each of this methods.

Please help!!!! Will provide helpful ratings for correct solution. Thank u

What are the volumes of two chambers seperated by a piston wall that allows heat exchange but the system as a whole is isolated? The wall is initially fixed but then is loosed to move. How do you find the volumes of both chambers once equilibrium is reached? Each chamber is filled with a different, single-atom gas. I am given an initial mol, temperature, and pressure of each chamber.

The following is a hypothetical binary phase diagram with various temperatures highlighted as (T) where n corresponds to a numeric value. Use the diagram to L T2 answer the following questions: 1.

100 atm 1 atm 0.118 atm 114 °C 184 °C 535 °C Temperature (not to scale) a.) Use the above generic phase diagram, clearly identify where you would find the following: Gas, Liquid, Solid, Triple Point, Draw arrows and label to indicate the six transitions (melting, freezing, sublimation, deposition, vaporization and condensation) b.) Based on the above phase diagram, what phase would you be in at a pressure of 50 atm and 300°C? c.) Based on the above phase diagram at what temperature in °C would vaporization occur under normal conditions? d.) If the pressure was 0.050 atm and 425°C, what phase would you be in? e.) If the pressure was 0.118 atm and temperature was 114°C, what phase(s) would you be in? f.) At approximately what temperature would the normal freezing point be in °C? g.) If the pressure was 0.105 atm and starting at a temperature of 32°C to 450°C what phase changes would occur (put in increasing temperature order). Pressure (not to scale)

You are working in a biology lab during your summer break. Your supervisor asks you to perform an experiment to find the effective spring constant (in N/m) of a partial molecule of DNA (deoxyribonucleic acid). You perform experiments and find that a single straight portion of a DNA molecule is 2.19 μm long. You then perform an activity that charges the ends of the molecule; each end becomes singly ionized: negative on one end, positive on the other. After the ends are charged, the molecule shrinks by 1.31% of its length. 1.21e-9

For the metals A and B, which are given below, create the hypothetical phase diagram between 500 ° C and 900 ° C temperatures.The melting temperature of metal A is 840 ° C.The solubility of B in A can be ignored at all temperatures.Metal B has a melting temperature of 730 ° C.The maximum resolution of A in B is 10 wt% A, which occurs at 600 ° C.At 500 ° C, the solubility of A in B is 6% A by weight.A eutectic 600 ° C and 74% B by weight - 26% by weight A are formed.The second eutectic occurs at 630 ° C and 59% B - 41% A by weight.A third eutectic occurs at 655 ° C and 39% B - 61% A by weight.A congress melting point is formed at 680 ° C and 52% B - 48% A by weight.A second congress melting point is formed at 655 ° C and 66% B - 34% A by weight.The intermetallic compound AB is present at 52 wt% B - 48 wt% A.The intermetallic compound AB2 is present at 66 wt% B to 34 wt% A.

c) What is the temperature of the iron heating element at x=30mm (in ∘C)? Use the origin defined in the given diagram. d) At which position x (in mm) does the iron heating element experience its highest temperature? e) In this scenario outlined in this question (constant heat generation under steady-state, 1-D conditions), can the temperature distribution in the iron ever be linear? Yes or No? Justify your reasoning.
