The term Big Bang defines that the Universe has expanded from the ancient hot and thick primary situation at some fixed time in the past.
Big Bang theory refers to the origin of the Universe. In the beginning, universe is very heavy and small hot ball of matter. It was a point no bigger than the head of a pin when all the things squished with each other and universe is expanded with huge explosion of energy. Due to expansion, it is cooled and results in the formation of Stars and galaxies. After sometime, atoms formed like helium and hydrogen.
Thus, statement (1), (3) and (4) is correct whereas statement (2) and (5) is incorrect.
N = (PV)/RT (T = 88.78 + 273 = 361.78K) (R = 22.4/273 = 0.082) = (5.49 x 22.03)/(0.082 x 361.78) = ? Put it into the calculator. It's hard to do that on a mobile phone.
