What is the major different between the particles in a liquid and a gas of the same substance at the same temperature?

Question

a
The particles in the gas are moving faster than the particles in the liquid
b
The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container
c
The particles in the liquid have higher masses than the particles in the gas
d
The particles the gas are separated, so they absorb less heat than normal, which is why gases are typically cooler than liquids

Answer 1

b
The particles in a liquid are still connected, but the particles in a gas have separated from each other and now fly around to fill the container
