Question

Unlike solids and liquids, gases change significantly when the conditions in which they are found are altered. True or False?

Answer 1

Yes, it is true that gases change significantly when the conditions in which they are found are altered unlike solids and liquids.

In gases, the molecules are very loosely packed while in solids and liquids are closer, so on applying pressure, the gases compress to a large extent (bringing molecules closer) while solids and liquids are generally incompressible and are not affected by pressure.

With the increase in the temperature, the gases expands ( thus resulting in increased spacing between gas molecules) while expansion does not take place much in solids and liquids.

Gases have no fixed volume. When they are shifted from one container/vessel to other, they take the shape of new vessel, filling completely inside the new vessel whether smaller or larger than the previous one. But the solids have fixed shape and volume and liquids have fixed volume but not fixed shape.
