The quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ
Quantity of Heat
From the question, we are to determine how much heat was transferred to the block of iron
Using the formula,
Q = mcΔT
Where Q is the quantity of heat
m is the mass
c is the specific heat capacity of the substance
and ΔT is the change in temperature
From the given information,
m = 0.400 kg
ΔT = 325 - 295 = 30 K
Putting the parameters into the equation, we get
Q = 0.400 × 462 × 30
(NOTE: Specific heat capacity of iron = 462 J/kg.K)
∴ Q = 5544 J
Hence, the quantity of heat that was transferred to the block of iron is 5544 J or 5.544 kJ
