Challenge Problems
Push your limits with challenges.
Question 1
You have a thin film of polymer with known electrical and thermal properties. Design a robust experimental setup using the 3Ο method to determine thermal conductivity and discuss potential challenges.
π‘ Hint: What environmental factors might affect your readings?
Question 2
Using laser flash analysis, you measure the temperature change of a material following a laser pulse. If the temperature rise is recorded at 75Β°C after 4 seconds, calculate the thermal conductivity, given the thickness and specific heat capacity values.
π‘ Hint: Try breaking down the process step by step!
