Which of the following substances A, B or C has the highest specific heat in temperature vs time graph.
A
B
C
All have equal specific heat
As we learn
Determination of specific heat capacity of a given solid -
- wherein
S= specific heat
H= Heat cap of calorie metre
= Temperature gain by object
= Temperature loss by body
m= mass of solid
M= mass of calorimeter
Since slope of C is lowest , hence its specific heat is highest.
