Question

If 8000 J of heat is used to heat the iron
rod of mass 40 kg from 60°C to 80°C,
determine the Specific heat capacity of
that iron rod.
O A) 5
O B) 50
0 C) 10
O D) 100​

Answer 1

Answer:The specific heat capacity is 10

Explanation: As we know Q = msdt so by solving this we can get like we have given Q = 8000j , Mass= 40kg and dt = (60-80) so Q= msdt 8000= 40 * (80-60)* S 8000/ 800 = S S= 10 ans.
