SHC and heat transfer
Iron=390
To raise temperature of 0.5kg iron from 22 to 34°c
To calculate the amount of heat transferred to the iron to raise its temperature, we need to make use of the specific heat capacity (SHC) of iron.
The equation for calculating the amount of heat transferred is:
Q = mcΔT
Where:
Q = Amount of heat transferred (in Joules)
m = Mass of the object (in kg)
c = Specific heat capacity of the material (in J/kg°C)
ΔT = Change in temperature (in °C)
In this case, the mass of the iron is given as 0.5 kg, and the specific heat capacity of iron is 390 J/kg°C.
So, we can plug these values into the formula:
Q = (0.5 kg) * (390 J/kg°C) * (34°C - 22°C)
Q = (0.5 kg) * (390 J/kg°C) * (12°C)
Q = 2340 J
Therefore, the amount of heat transferred to raise the temperature of 0.5 kg of iron from 22°C to 34°C is 2340 Joules.
