Using heat balance, mass times heat capacity times temperature difference, the balance looks like:

3.35 * 1000 g * 4.18 J / g C * (20-T) = 1.62 * 1000 g* 80 * 4.1858 J /g + 1.62 * 1000 g * 4.18/2  J / g C * (10.2 C) + <span>1.62 * 1000 g * 4.18 J /gC * (T-0)

Final temperature, T is equal to 14.29 C</span>

What average energy of particles does temperature measures?​
sertanlavr [38]

Answer:

Well, temperature is simply an average measure of the kinetic energy for particles of matter. Another way of putting it would be that temperature simply describes the average vibration of particles. Because the motion of all particles is random, they don’t all move at the same speed and in the same direction.
