| What amount of heat is needed to heat 100 grams of copper from 10 degrees to 20 degrees. Copper heat capacity is 400 J / kg.
Initial data: m (copper mass) = 100 g or 0.1 Kg; t0 (copper temperature before heating) = 10 ºС; t (copper temperature after heating) = 20 ºС.
Reference values: by condition C (specific heat of copper) = 400 J / (kg * ºС).
The required amount of heat to change the temperature of 100 grams of copper can be calculated by the formula: Q = C * m * (t – t0).
Let’s perform the calculation: Q = 400 * 0.1 * (20 – 10) = 400 J.
Answer: To heat 100 grams of copper, 400 J of heat is required.
