Answer:
The total amount of heat energy released by the water is 20,900 J
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
The sensible heat of a body is the amount of heat received or transferred by a body when it undergoes a temperature variation without there being a change in physical state (solid, liquid or gaseous). Its mathematical expression is:
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 is the variation in temperature.
In this case:
- Q=?
- c= 4.18 [tex]\frac{J}{g*C}[/tex]
- m= 200 g
- ΔT= Tfinal - Tinitial= 50°C - 25°C= 25°C
Replacing:
Q= 4.18 [tex]\frac{J}{g*C}[/tex] *200 g* 25°C
Solving:
Q=20,900 J
The total amount of heat energy released by the water is 20,900 J
