✔ 最佳答案
Energy= mass*c*change in temp

C = 47.8/(13*1.77)
C = 2.08

Heat added, E = 47.8 J
Mass, m = 13.0 g
Temperature rise, ΔT = 1.77°C

E = m c ΔT
c = E / (m ΔT)

Heat capacity, c = (4.78 J) / [(13.0 g) × (1.77°C)] = 0.208 J / (g °C)

One calorie is the amount of energy required to raise the temperature of 1 gram of water by 1 degree celsius. One calorie is equal to 4.181 joules.
