Question

How much heat would be absorbed by 75g. of iron when heated from 22C to 28C?

Answer 1

Answer: 1881 J
Explanation:
ΔH = MCΔT
ΔH = to the amount of energy or change in energy (J)
M = mass of substance
C = waters specific heat capacity
ΔT = change in temperature
and so ΔH = 75 * 4.18 * ( 28-22 ) = 1881 J

Hope that helps! Have a good day :)
