$\huge\color{purple}{ \colorbox{pink}{\colorbox{white} {Aɴsᴡᴇʀ ✔︎✔︎ }}}$

Temperature, T1 = 27.5°C Resistance of the silver wire at T1, R1

= 2.1 Ω

Temperature, T2

= 100°C Resistance of the silver wire at T2, R2

= 2.7 Ω Temperature coefficient of silver

= α It is related with temperature and resistance as

In the attachment

Therefore, the temperature coefficient of silver is 0.0039°C−1.
