how much heat is required to change 5 grams of iron to 10c
To determine the amount of heat required to change the temperature of a substance, we need to use the specific heat capacity (C) of the material. The specific heat capacity represents the amount of heat needed to raise the temperature of a given mass of a substance by a certain degree.
The specific heat capacity of iron is around 0.45 joules per gram per degree Celsius (J/g°C). So let's calculate the heat required using this value:
Heat (Q) = Mass (m) x Specific Heat (C) x Change in Temperature (ΔT)
Given:
Mass (m) = 5 grams
Specific Heat (C) = 0.45 J/g°C (approximate value)
Change in Temperature (ΔT) = 10°C
Plugging these values into the formula:
Q = 5 g x 0.45 J/g°C x 10°C
Q = 22.5 J
Therefore, approximately 22.5 joules of heat would be required to change 5 grams of iron by 10 degrees Celsius.
