Question

At very high pressures, gases become ____________ and will eventually _______________. A) more dense; become hotter B) more dense; change to a liquid or solid C) less dense; combust D) less dense; turn into a liquid

Answer 1

The answer is B; At very high pressures, gases become more dense and will eventually change to a liquid or solid.

Answer 2

Answer:

The correct answer is B.

Explanation:

Ideal and real gases behave similarly when subjected to high pressures. Depending on the temperature at which they are found if this remains constant the viscosity of the gas will increase. If the temperature is low, the gas will go from a gaseous state to a solid-state, whereas for higher temperatures, it will go to a liquid state. This is easily observed in a phase diagram.

Have a nice day!
