Determine the amount of heat required to heat 20 g of aluminum from 20 C to 30 C. Specific heat capacity of aluminum 910 J / kg С
Initial data: m (mass of heated aluminum) = 20 g (20 * 10-3 kg); t0 (initial temperature of aluminum) = 20 ºС; t (aluminum temperature at the end of heating) = 30 ºС.
Reference data: according to the condition Ca (specific heat capacity of aluminum) = 910 J / (kg * ºС).
The required amount of heat for heating 20 grams of aluminum is calculated by the formula: Q = Ca * m * (t – t0).
Calculation: Q = 910 * 20 * 10-3 * (30 – 20) = 182 J.
Answer: You need 182 Joules of heat.
