SUMMARY
The final temperature of a mixture of oxygen at 105 K and room air at 307 K, mixed at equal mass flow rates, is calculated using the specific heat capacities of both substances. The correct formula is Q=mcΔT, where the heat transfer is equal for both components. The resulting temperature of the mixture is determined to be approximately 210 K, based on the equation (105 x 918 + 307 x 1012) / (918 + 1012). This calculation confirms the validity of the approach taken in the discussion.
