216 j of energy is required to raise the temperature of aluminum from 15o to 35oc. calculate the mass of aluminum. (specific heat capacity of aluminum is 0.90 joc-1g-1).
energy is supplied to aluminium to raise the temperature of aluminium. we can use the following equation to calculate the mass of aluminium H = mcΔt H - heat energy supplied m - mass of material c - specific heat capacity of aluminium Δt - change in temperature - 35 °C - 15 °C = 20 °C substituting the values in the equation 216 J = m x 0.90 J°C⁻¹g⁻¹ x 20 °C m = 12 g mass of aluminium is 12 g
