The correct statement about absolute zero is A: At absolute zero, the volume of an ideal gas is zero. This theoretical temperature is defined as 0 Kelvin, equivalent to -273.15 degrees Celsius, at which all molecular motion ceases. Absolute zero is a crucial concept in physics but has not been reached in practice.
