Answer: 13.23 degrees C
Explanation:
Q= mc(Tfinal-Tinitial)
(Use the specific heat equation)
The final temperature of the water after the absorption of 12.28 kJ of energy has been 13.23 [tex]\rm ^\circ C[/tex].
Specific heat can be defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius.
The specific heat can be expressed as:
Heat = mass [tex]\times[/tex] specific heat [tex]\times[/tex] (Final temperature - Initial temperature)
From the given:
12.28 kJ = 325 g [tex]\times[/tex] 4.184 J/g[tex]\rm ^\circ C[/tex] [tex]\times[/tex] (Final temperature - 4.2 [tex]\rm ^\circ C[/tex])
12.28 [tex]\times[/tex] 1000 J = 1,359.8 (Final temperature - 4.2 [tex]\rm ^\circ C[/tex] )
12,280 = 1,359.8 (Final temperature - 4.2 [tex]\rm ^\circ C[/tex] )
9.03 = Final temperature - 4.2 [tex]\rm ^\circ C[/tex]
Final temperature = 13.23 [tex]\rm ^\circ C[/tex]
The final temperature of the water after the absorption of 12.28 kJ of energy has been 13.23 [tex]\rm ^\circ C[/tex].
