Answer: (d)-Silver
Explanation:
Given
The mass of sample is [tex]m=18\ gm[/tex]
It is heated from [tex]21.5^{\circ}C[/tex] to [tex]89^{\circ}C[/tex]
heat energy absorbed is [tex]292\ J[/tex]
Heat absorbed is given by [tex]Q=mc\Delta T[/tex]
Insert the values
[tex]\Rightarrow 292=18\times c\times [89-21.5]\\\Rightarrow 292=18\times c\times 67.5\\\\\Rightarrow c=\dfrac{292}{1215}\\\\\Rightarrow c=0.24\ J/g^{\circ}C[/tex]
As per the table, it is Silver
