Solution

The temperature of the milkshake after it has reached thermal equilibrium will be the same as the temperature of the fridge, which is 5 °C. This is because when two objects of different temperatures come into contact, they will exchange heat until they reach the same temperature, a state known as thermal equilibrium. In this case, the milkshake will cool down and the fridge will absorb the heat until they are both at the same temperature.
