SUMMARY
The discussion revolves around calculating the specific heat capacity of an unknown liquid mixed with water. The mixture consists of 75g of the unknown liquid at 25 degrees Celsius and 60g of water at 90 degrees Celsius, resulting in a final temperature of 65 degrees Celsius. The specific heat capacity of the unknown liquid is calculated to be approximately 2.0905 J/g°C using the formula Q = mcΔT, where the heat lost by water equals the heat gained by the unknown liquid. The conclusion suggests that the unknown liquid could be steam or ice, but the temperature conditions indicate it must be a liquid, prompting further investigation into specific heat tables.
