Q = m x C x ΔT. 
Where.... 
Q = Quantity of Heat (Released or Absorbed). Joules, calories or Btu. 
m = Mass (grams) of substance being heated, cooled or changing state. 
C = Specific Heat Capacity (J/g/°C; cal/g/°C; Btu/lb/°F). 
(Also, Molar C = Molar Heat Capacity J/mol.K (or °C). 
ΔT = Difference in Temperature.(ΔT°C; or ΔT°F). 

(ΔTcan be in °C or K (Kelvin) or, in °F or R (Rankine)

Q = 55g x 4.179 (100c - 37c)

Q =14480 j/kg
