Question

state three important property of:Gas,a solid, a gas​

Answer 1

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy. The particles move very fast and collide into one another, causing them to diffuse, or spread out, until they are evenly distributed throughout the volume of the container.

When more gas particles enter a container, there is less space for the particles to spread out, and they become compressed. The particles exert more force on the interior volume of the container. This force is called pressure. There are several units used to express pressure. Some of the most common are atmospheres (atm), pounds per square inch (psi), millimeters of mercury (mmHg) and pascals (Pa). The units relate to one another this way: 1 atm = 14.7 psi = 760 mmHg = 101.3 kPa (1,000 pascals

Answer 2

$\huge{\underline{\boxed{\mathbb{answer}}}}$

$\color{green} {} solid . property$

List six properties of solids, and explain each in terms of the kinetic-molecular theory of solids. Definite shape, definite volume, definite melting point, high density, incompressibility, and low rate of diffusion.

$\color{red} {} Liquid.property$

All liquids show the following characteristics:

Liquids are almost incompressible. In liquids molecules are pretty close to each other. ...

Liquids have fixed volume but no fixed shape. ...

Liquids flow from higher to lower level.

Liquids have their boiling points above room temperature, under normal conditions.
