Answer:
DUE TO GRAVITATIONAL COLLAPSE SOLAR SYSTEM IS FORMED , ORBITS ARE CURVED TRAJECTORIES AND SIZE AND COMPOSTION OF PLANET ARE VERY UNIQUE AND COMPOSED OF ROCKS AND METALS and evolution of solar system has began 4.5 billion years ago,due to gravitational collapse of a small particle from a giant cloud.
Answer: 85.62 L represents volume (V).
Explanation:
Volume is defined as the amount or quantity of a given substance or an object.
According to ideal gas equation:

P = pressure of gas = 4.95 atm
V = Volume of gas = 85.62 L
n = number of moles
R = gas constant =
T =temperature =
Thus 85.62 L represents volume (V).
