Thermochemistry

Question

Calculate the amount of energy required to raise the temperature of 10.5 g of iron from 25.2°C To 30.5°C. The specific heat capacity of iron is 0.444J/g°C

Give the quantity and the unit (e.g. 3.5 cm).

Answer 1

The formula you want to use is q = mCΔT

q = heat = ?

m = mass = 10.5 g

C = specific heat = 0.444 J/g/degree

ΔT = change in temp = 30.5 - 25.2 = 5.3 degrees

plug in the values and solve for q

q = (10.5)(0.444)(5.3)

q = 24.7 J
