Taking into account the definition of calorimetry, the energy released is 2283.93 J.
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
In this way, between heat and temperature there is a direct proportional relationship. the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where:
In this case, you know:
Replacing in the definition of calorimetry:
Q = 0.3845 [tex]\frac{J}{gC}[/tex]× 26.4 g× (-225 C)
Solving:
Q= -2283.93 J
Finally, the energy released is 2283.93 J.
