Question

How much heat is required to raise by 10.30°C the temperature of 1.2 kg of iron?

Answer 1

Q1 = c1•m1 •Δt1 =4180•1.2•10.3 = 51665 J
Q2 = c2•m2• Δt2 =444•1.2•10.3 = 5488 J

Answer 2

Calculate the heat required to raise the temperate of 10kg of copper perform from 20c to 30c specific capacity of copper= 400j/kgk
