Which of the following statements is correct concerning the gas phase? view available hint(s) hint 1. how gases differ from solids and liquids which of the following statements is correct concerning the gas phase? when pressure is applied to a gas, its volume increases. a gas expands spontaneously to fill its container. depending on their chemical nature, two or more gases can form either a homogeneous or heterogeneous mixture. the volume of a gas is always less than the volume of its container.

A gas expands spontaneously to fill its container.

Explanation:

The molecules of a gas are cluttered and distant one from other, so when gas is put in a container, the molecules occupy all the space, so it expands spontaneously, and the volume is always equal to the volume of the container.

By the equation of the ideal gas PV = nRT, we can notice that pressure and volume are indirectly proportional, so when pressure is applied to gas it compress, and the volume decreases.

A gas mixture is always homogeneous, because of the distance between the molecules of the compounds, so it's impossible to determinate the phases.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
