The final temperature of the system is obtained as 26 degrees
What is equilibrium temperature?
In a closed system, thermal equilibrium occurs when the average kinetic energy of the molecules is constant throughout the system, meaning there is no net heat flow between different parts.
Heat lost by Al = Heat gained by water
-(25.5 * 0.903 * (T - 65.9) = (55.2 * 4.2 * (T - 22.1)
-23.03T + 1517.68 = 231.84T - 5123.66
-23.03T - 231.84T = - 5123.66 - 1517.68
-254.87T = -6641.34
T = 26 degrees
Missing parts;
A 25.5 g aluminum block is warmed to 65.9 ˆ˜C and plunged into an insulated beaker containing 55.2 g water initially at 22.1 ˆ˜C. The aluminum and the water are allowed to come to thermal equilibrium.
