Question) Compare work done in extending mechanically with thermal energy gain to achieve the same extension.
For any extension, determine the value of (work down by mechanical extension ÷ thermal energy required for extension)
The only way I can think to link force and distance (which is work done) is using stress ÷ strain = youngs modulus. In terms of thermal energy I think specific heat capacity × mass × change in temp is the only way. I'm really confused as to how these would link.
Thank you very much in advance.
