How much heat is needed to heat a 2 kg brick from 20 degrees to 53 degrees?
| August 19, 2021 | education
Problem data: m (the mass of the brick taken) = 2 kg; t0 (initial brick temperature) = 20 ºС; t (final temperature) = 53 ºС.
Constants: CK (specific heat capacity of a brick) = 880 J / (kg * K).
The heat expended for heating the brick taken is calculated by the formula: Q = CK * m * (t – t0).
Calculation: Q = 880 * 2 * (53 – 20) = 58,080 J.
Answer: To heat the brick taken, 58,080 Joules of heat must be spent.
