The absolute zero is a temperature at which _______
-
- molecular motion in a gas would cease
- water freezes
- all gases become liquid
- all gases become solid
- molecular motion in a gas would cease
Correct Option: A
Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. It is the point at which all motion in matter stops. By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
