The temperature of an ice cube when it is removed from a freezer depends on the temperature of the freezer and how long the ice cube has been inside. Typically, the temperature inside a household freezer is set to around -18°C (0°F) to -24°C (-11°F).
When you remove an ice cube from a freezer that has been at these temperatures, the ice cube itself will also be at a similar temperature, so it will be very cold, close to -18°C to -24°C (0°F to -11°F). However, once the ice cube is exposed to warmer room temperatures, it will begin to slowly melt and its temperature will gradually rise towards the melting point of ice, which is 0°C (32°F).
In real-life scenarios, the temperature of the ice cube will start changing the moment it is removed from the freezer due to the heat exchange with the surrounding air. Therefore, it is essential to specify the duration since the ice cube was removed from the freezer if you want to know its exact temperature at a given time.
