To calculate the amount of heat entering or leaving a system, the equation
Q=mcT is used.
Where
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.
25°Câ’0°C=25°C
Q=25grams⋅4.19J/g°C⋅25°C
Q=2618.75J
