SUMMARY
The specific heat capacity of an unknown material can be determined using the principle of heat transfer, specifically through the equation Q = mcΔT. In this scenario, a 50g sample heated to 80°C is placed in a calorimeter containing 100g of water at 10°C, resulting in a temperature increase of 5°C for the water. The heat capacity of the calorimeter is 20 J/K, which must also be accounted for in the calculations to find the specific heat capacity of the unknown material.
