Answer:
the heat capacity of the bolt is 13.9 J/K
Explanation:
J/K is short of " joule per kelvin", is the international system unit of heat capacity
heat energy = (mass of substance)(specific heat)(change in temperature)
Q = mc∆T
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)
∆ is a symbol meaning "the change in"
∆T = change in temperature (Kelvins, K)
Heat gained by water = heat lost by copper = Q = mC∆T = (50 g)(4.18 J/g/deg)(5 deg) = 1045 J = C x ∆T
C = 1045 J/75 = 13.9 J/deg
