Two students are running down the hallway towards each other. Student 1 has a mass of 107kg and is running to the right at 4.1m/
s. Student 2 has a mass of 97kg and is running to the left at 7.1m/s. If they strike in an elastic collision, what is the velocity of student 2 if student 1 moves at 6.55m/s to the left after the collision?
To determine the heat released by the process of condensation, we simply multiply the amount of the gas that condensed to the latent heat of vaporization. We do as follows:
Heat released = 21 J/g (12.0 g ) = 252 J of heat released
