Answer:
The specific heat of the unknown metal is 1.26*10⁻⁴ [tex]\frac{kcal}{g* C}[/tex]
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat occurs when heat added or removed from a substance causes a temperature change in it and is calculated by:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c and where ΔT (Tfinal - Tinitial) is the variation in temperature
In this case:
- Q= 2.93 kcal
- c= ?
- m= 183.4 g
- ΔT= 126.3 °C
Replacing:
2.93 kcal= c* 183.4 g*126.3 °C
Solving:
[tex]c=\frac{2.93 kcal}{183.4 g* 126.3 C}[/tex]
c= 1.26*10⁻⁴ [tex]\frac{kcal}{g* C}[/tex]
The specific heat of the unknown metal is 1.26*10⁻⁴ [tex]\frac{kcal}{g* C}[/tex]
