The density of ice at 0 degrees Celsius is approximately 917 kilograms per cubic meter. To find the volume of 1 kilogram of ice, we can use the formula:

Volume = Mass / Density

Volume = 1 kilogram / 917 kilograms per cubic meter

Volume ≈ 0.0011 cubic meters

Since 1 cubic meter is equal to 1000 liters, we can convert the volume to liters:

Volume ≈ 0.0011 cubic meters * 1000 liters / 1 cubic meter

Volume ≈ 1.1 liters

Therefore, the volume of 1 kilogram of ice at 0 degrees Celsius is approximately 1.1 liters.
