Answer:

4,390'538,259'694,256 kilometers

Explanation:

Light years is a distance measure that represents the distance the light travels in the vacuum in a year and it is approximately  equal to 9'460,730'472,580.8 kilometers. Then, if V391 Pegasi is 4,570 light years away from earth:

4,570(light year) * \frac{9'460,730'472,580.8 (kilometers)}{1(light year)}  = 4,390'538,259'694,256(kilometers)

Answer:

The correct option is;

The gas particles move faster, have the same molecular composition, and have weaker attractions between them than the liquid particles

Explanation:

The properties of the gas molecules in comparison to liquids are

1) The gas molecules are widely spread out

2) After evaporation and while in conditions favorable to the gaseous state, the kinetic energy of a gas is larger than the inter molecular attractive forces

3) A gas fills the container in which it is placed

For liquids

1) There are strong intermolecular forces holding the molecules together in a liquid

2) Liquid attractive forces in a liquid are strong enough to hold neighboring molecules

3) The volume of a liquid is definite.
