A. 2,354,000 J
B. 1,170,000 J
C. 56,891 J
D. 10,650 J
Answers
Answer:B. 1,170,000 JExplanation:Given;mass of lead block, m = 40 kginitial temperature, t₁ = -25 ⁰Cfinal temperature, t₂ = 200 ⁰CThe heat absorbed the lead block is calculated as;H = mcΔtwhere;c is the specific heat capacity of lead = 130 J/kg⁰CH = 40 x 130 x (200 - (-25))H = 40 x 130 x (200 + 25)H = 40 x 130 x 225H = 1,170,000 JTherefore, the heat absorbed the lead block is 1,170,000 J
