Question on: JAMB Physics - 2024
How many joules of heat are given out when a piece of iron of mass 60 g and specific heat capacity 460 J/kg·K cools from 75 ºC to 35 ºC?
A
1000 J
B
1050 J
C
1067 J
D
1104 J
Ask EduPadi AI for a detailed answer
Correct Option: D
Here's how to solve the problem:
- Identify the formula: Q = mcΔT, where m = mass, c = specific heat capacity, ΔT = change in temperature.
- Convert mass to kilograms: m = 60 g = 0.06 kg
- ΔT = 75 - 35 = 40 ºC
- Q = 0.06 kg x 460 J/kg·K x 40 K = 1104 J
