To calculate the heat absorbed by the iron skillet, we need to use the heat capacity formula:
Q = m * c * ΔT
Where:
Q = Heat absorbed (in Joules)
m = Mass of the iron skillet (in grams)
c = Specific heat capacity of iron (in J/g·°C)
ΔT = Change in temperature (in °C)
First, let's convert the mass from grams to kilograms:
m = 70g = 70/1000 = 0.07 kg
Next, we need to find the specific heat capacity of iron. The specific heat capacity of iron is approximately 0.45 J/g·°C.
Now we can calculate the change in temperature:
ΔT = 110°C - 24°C = 86°C
Plugging the values into the formula, we get:
Q = 0.07 kg * 0.45 J/g·°C * 86°C
Calculating that, we find:
Q = 270.9 J
Therefore, the iron skillet absorbs approximately 270.9 Joules of heat.
