Answer: Option (4) is the correct answer.
Step-by-step explanation:
STP means standard temperature and pressure, that is, at STP temperature is 0 degree Celsius, volume is 22.41 L, and pressure is 1.00 atm.
Entropy means that degree of randomness, that is, particles of a matter will move rapidly from one place to another.
In gases, molecules move randomly as they are held by weak Vander waal forces.
Thus, out of the given options, at STP, a sample of
element has the highest entropy.
