Several works have proposed experiments to determine thermal physical constants of materials, such as finding the coefficient of linear expansion.1–4 As Dajbych5 and Polak et al.6 have shown, physical constants can be verified by measuring the frequency of a plucked high-carbon steel wire on a guitar. Building on our previous work,6,7 we have extended our method to verify the coefficient of linear thermal expansion, αT, through an accessible procedure directed at introductory physics education.
