Question : Absolute zero is a temperature at which
Option 1: Molecular motion in a gas would cease
Option 2: Water freezes
Option 3: All gases become liquid
Option 4: All gases become solid
Correct Answer: Molecular motion in a gas would cease
Solution : The answer is Molecular motion in a gas would cease .
Absolute zero is the temperature at which all molecular motion stops. It is the lowest temperature on the Kelvin scale and equals -273.15 degrees Celsius. At absolute zero, all particles have the lowest possible energy since they are in their ground state. This is because the entire structure loses all kinetic energy.
