Answer is:
Agree
Answer is:
4/7
Answer is:
-273 Degree C
Explanation:
Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvins.
At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.
According to kinetic theory of gases, the absolute zero temperature is attained when kinetic energy of the molecules is zero.
Answer is:
