Two samples of water are mixed in a styrofoam calorimeter. Sample 1 has a mass of 60.0 g and an initial temperature of 20.0°C. Sample 2 has a mass of 25.0 g and an initial temperature of 100.0°C. Specific heat of liquid water is 4.184 J/gK.
From the following, select the one that is closest to the final temperature of the system after thermal equilibrium is achieved. Assume all the energy remains in the calorimeter.
Question 16 options:
15.4°C
59.9°C
43.5°C
48.1°C
