a 2kg block of iron is given 10kj of energy and its temperature rises by 10c. what is the specific heat capacity of iron?
To find the specific heat capacity of iron, we can use the formula:
Heat Energy (Q) = mass (m) × specific heat capacity (c) × temperature change (ΔT)
Given:
Mass (m) = 2 kg
Heat Energy (Q) = 10 kJ = 10,000 J
Temperature change (ΔT) = 10 °C = 10 K (since Celsius and Kelvin scales have the same magnitude)
We need to rearrange the formula to solve for the specific heat capacity (c):
c = Q / (m × ΔT)
Now, substitute the values:
c = 10,000 J / (2 kg × 10 K)
c = 500 J / (kg × K)
The specific heat capacity of iron is 500 J/kg*K.
