Answer: it’s B
Explanation:
Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
90 grams due to laws of conservation of mass. Input mass always = output mass. It may come out in a different form but it's always the same mass.
