Question 5 of 7
5. Question
In the simulation of the heated wire performed in thermal-conductive simulation, imagine that all the surfaces of the glass encapsulation are thermally insulated except the top surface which is kept at 250 K by a thermoelectric cooler. Also, assume that the wire has a cross-section of 2 by 2 um.
What is the temperature of the hottest point in the simulation (in the units of kelvin) when a voltage of 2V is applied to the wire? (Hint: Use the visualizer window to view the temperature profile and its range)

Question 7 of 7
7. Question
In the transient heat flow simulation of a glass thin-film with a graphene layer as performed in the “transient simulation” subsection, the right edge of the film is kept at 400K up to 200us.
If the right edge of the thin film is suddenly brought back from 400K to room temperature at 200us, from the moment that this change happens, how long does it take for the temperature difference across the entire thin film to become less than one degree?
Enter your answer in the units of us rounded to the nearest integer value.
