Answer:
The heat released when the temperature of 60 g of water decreases from 75 degrees Celsius to 27 degrees Celsius is -12,049.92 J.
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state or phase change. Sensible heat is measured by the expression:
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:
Replacing:
Q= 4.184 [tex]\frac{J}{g*C}[/tex] *60 g* (-48 C)
Q= -12,049.92 J
The heat released when the temperature of 60 g of water decreases from 75 degrees Celsius to 27 degrees Celsius is -12,049.92 J.
