Question

suppose you have three identical test tubes that contain equal masses of a solid, liquid, and gas form of the same substance. which form of the substance has the largest volume and why? a solid: it has the hardest surface. b none: all of them have the same volume. c gas: it expands to fill the container. d liquid: it takes the shape of the container.

Explanation:

In the gas - phase, particles are more spread out and have higher kinetic energy compared to solids and liquids. Gases expand to fill the entire volume of their container due to weak intermolecular forces and high mobility of particles.

Answer:

C. Gas: It expands to fill the container
