How much heat is needed to heat one ton of lead by 5 degrees?
| March 31, 2021 | education
To determine the cost of heat for heating the taken ton of lead, we will use the formula: Q = Cc * m * Δt.
Variables and constants: Cc – specific heat capacity of lead (Cc = 140 J / (kg * K)); m is the mass of the lead being heated (m = 1 t = 1 * 10 ^ 3 kg); Δt – temperature change (Δt = 5 ºС).
Calculation: Q = Cc * m * Δt = 140 * 1 * 10 ^ 3 * 5 = 700 * 10 ^ 3 J (700 kJ).
Answer: To heat a ton of lead, you need to spend 700 kJ of heat.
