Question

A mass of stainless steel spoon is 0.04 kg and specific heat is $0.50kJ/kg{\times }^{o}C$. Then calculate the heat which is required to raise the temperature ${20}^{o}C$ to ${50}^{o}C$ of the spoon.

• A. 200 J
• B. 400 J
• C. 600 J
• D. 800 J
• E. 1,000 J

Answer 1

The correct option is C 600 J

The required heat, $Q=ms\Delta T=0.04\times (0.50\times {10}^3)\times (50-20)=600J$
