How much heat will be released when a gram of zinc is cooled from 100 to 10 degrees?

univerkov | May 28, 2021 | education

m = 1 g = 0.001 kg – mass of zinc
с = 380 J / kg * С – specific heat of zinc
t1 = 100 C
t2 = 10 C
Q -?
Q = C * m * (t2-t1)
Q = 380 * 0.001 * (10-100) = – 34.2 J
Answer: Q = 34.2 J of energy released during cooling of zinc
