The time it takes for a can to get cold in a refrigerator or freezer can vary depending on several factors, including the initial temperature of the can, the temperature settings of the appliance, and the specific conditions of the refrigerator or freezer.
In a typical household refrigerator set to around 4°C (40°F), it may take anywhere from 1 to 3 hours for a can to reach a noticeably cold temperature. However, it's important to note that this is just an estimate, and the actual time can vary.
If you want to cool a can more quickly, you can place it in a freezer instead. In a standard freezer set to approximately -18°C (0°F), a can may cool down significantly within 30 minutes to an hour. Again, the exact time can vary depending on the factors mentioned earlier.
It's worth mentioning that if you want to cool beverages rapidly, you can use methods such as placing the can in a container filled with ice and water or rotating the can in a salted ice bath. These methods can help accelerate the cooling process and reduce the time required to reach a cold temperature.
Remember that if you place a carbonated beverage in the freezer for too long, it may freeze and expand, potentially causing the can to burst or explode. Therefore, it's important to monitor the time and remove the can from the freezer before it reaches freezing temperatures.
