Question

How much heat is required to increase the temperature of 1 kg of steel from 21 °C to 22 °C?

Answer 1

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
