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