Yes, 10 degrees Fahrenheit (-12 degrees Celsius) is generally cold enough for a freezer. Freezers are designed to maintain temperatures below the freezing point of water, which is 32 degrees Fahrenheit (0 degrees Celsius). Most household freezers operate at temperatures between -10 and 0 degrees Fahrenheit (-23 to -18 degrees Celsius) to keep food frozen and preserve its quality. Therefore, a temperature of 10 degrees Fahrenheit would still be sufficiently cold for a freezer to function properly.
