How much heat needs to be imparted to aluminum weighing 0.1 kg to heat it up to 20 degrees?
| February 7, 2021 | education
To determine the heat that must be transferred to aluminum when heated, we use the formula: Q = Ca * m * Δt, where Ca is the specific heat capacity of aluminum (Ca = 920 J / (kg * K)); m is the mass (m = 0.1 kg); Δt (required change in aluminum temperature) = 20 ºС.
Let’s perform the calculation: Q = Q = Ca * m * Δt = 920 * 0.1 * 20 = 1840 J.
Answer: To heat aluminum, you need to spend 1840 J of heat.
