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

The particles in the gas are moving faster than the particles in the liquid

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

The particles in the liquid have higher masses than the particles in the gas

The particles the gas are separated, so they absorb less heat than normal, which is why gases are typically cooler than liquids
