Answer: c = 710 J/kg°C or 0.71 J/g°C
Explanation: Heat is expressed in the formula Q = mc∆T. Derive to find the specific heat c. So the formula will become c = Q / m∆T
c = Q / m∆T
= 42600 J / 2 kg ( 55°C - 25°C )
= 710 J /kg°C
Or can be expressed by converting kg to g.
c = 0.71 J /g°C

Answer:
Answer is C because in exothermic reactions, energy releases.
in Cellular respiration,
ATP+H20 (water) = ADP+ Pi + Energy
So celullar respiration is exothermic and releases energy
