Explanation:
i it true?
Answer is: 5,170 J of heat is absorbed by the reaction.
ΔT= 28.50°C - 27.45°C = 1.05°C; temperature change.
m = 1400 g; mass of substance.
cp= 3.52 J/g·°C, specific heat capacity of the substance.
Q = m(granite) · ΔT(granite) · cp(granite).
Q = 1400 g · 1.05°C · 3.52 J/g·°C.
Q = 5,170 J; amount of energy gained.
