Question

What is the specific heat capacity of a penny?  Look up what metals make up a penny and their specific heat capacities.  How does this compare to the specific heat capacity that you determined? 

 

 

 

The specific heat capacity of a penny is 0.098 Cal /g °C  this is the results in my lab, help me with the question above

Penny

  1. Heat of Penny = -77.0 cal
  2. Mass =37.4 g
  3. Initial Temperature =45.6 °C
  4. Final Temperature = 24.6 °C
  5. Temperature change = -21.0 °C
  6. Specific Heat Capacity of a Penny (Cp)= 0.098 Cal /g °C
