Question

If 81 J of Heath is added to pure gold coin with a mass of 12 g, what is the temperature change? The specific heat capacity of gold is 0.128J/g^C

Answer 1

Equate 81 Joules to the product of the specific heat of gold, the mass of the gold,

and the change in temperature sought.

81 J = [0.128 J/(g • °C)] × {12 g} × (ΔT)°C.

Dimensions on the right side of the equation go to Joules in agreement with the

left side and ΔT reduces to [81/0.128/12] or 52.734375 in Degrees Celsius as

the change in temperature.
