How much energy is required to raise the temperature of 11.6 grams of solid magnesium from 21.5 C to 37.3 C ?

Answer 1

q = mC∆T

q = heat energy = ?

m = mass = 11.6 g

C = specific heat for magnesium = 1.0467 J/gº (look it up in a table)

∆T = change in temperature = 37.3 - 21.5 = 15.8º

q = (11.6 g)(1.0467 J/gº)(15.8º)

q = 191.8 J = 192 J (3 sig. figs.)
