ii) Entropy.

Question 5: 10 kg of solid body with a specific heat of 300 J/kg K should be heated from 15^o C to 50^o C. Compute the amount of heat to be transferred to it. What will be its temperature if twice of this heat is transferred.

Question 6: When 3.175 kg of solid body is heated with 10 kJ of heat, its temperature is found to increase from 30^oC to 45^oC. Compute its specific heat.
