A) \[{{S}_{A}}>{{S}_{B}}>{{S}_{C}}\]
B) \[{{S}_{B}}={{S}_{C}}<{{S}_{A}}\]
C) \[{{S}_{A}}={{S}_{B}}={{S}_{C}}\]
D) \[{{S}_{A}}={{S}_{B}}>{{S}_{C}}\]
Correct Answer: D
Solution :
If R is rate of heating, \[\Delta Q=ms(\theta )\] \[Rt=ms\theta \Rightarrow \theta =\left( \frac{R}{ms} \right)t\] Slope of\[\theta -t\]curve\[=\frac{R}{ms}=\tan \phi \] From it we conclude, \[{{S}_{A}}={{S}_{B}}>{{S}_{C}}\] Because\[\frac{R}{ms}\]for both A and 6 are same.You need to login to perform this action.
