Question

recall the juice cooled from 21.0 °c to 6.0 °c. what is the final temperature of the al \ice cubes\ when the system reaches equilibrium? t_f = ? °c +6.0℃ +15 °c -15 °c -6.0 °c

Explanation:

When a system reaches thermal equilibrium, all components in the system will have the same final temperature. The juice cooled from 21.0 °C to 6.0 °C, and the Al "ice cubes" will reach the same temperature as the juice at equilibrium because heat will transfer until thermal equilibrium is achieved (where the temperature of all parts of the system is equal). So the final temperature of the Al "ice cubes" should be the same as the final temperature of the juice, which is 6.0 °C.

Answer:

+6.0°C
