Question
The quantity of heat required to raise the temperature of 500 g of iron by 2°C, given that the specific heat capacity is 500 J/(kg °C), is: a. 250 kJb.2 Jc.500 kJd.0.5 kJ
Solution
The quantity of heat (Q) required to raise the temperature of a substance can be calculated using the formula:
Q = mcΔT
where: m = mass of the substance c = specific heat capacity of the substance ΔT = change in temperature
Given: m = 500 g = 0.5 kg (since 1 kg = 1000 g) c = 500 J/(kg °C) ΔT = 2°C
Substituting these values into the formula, we get:
Q = 0.5 kg * 500 J/(kg °C) * 2°C = 500 J
Therefore, the quantity of heat required to raise the temperature of 500 g of iron by 2°C is 500 J.
So, the correct answer is not listed in the options provided.
