Answer:
466J
Explanation:
Given parameters:
Mass of steel = 1kg = 1000g
Initial temperature = 21°C
Final temperature = 22°C
Unknown:
Amount of heat required for this temperature increase = ?
Solution:
To solve this problem, we use the expression below:
So;
Heat absorbed = mass x specific heat of steel x change in temperature
Specific heat of steel = 0.466J/g°C
Therefore;
Heat absorbed = 1000 x 0.466 x (22 - 21) = 466J
