Answer: D. They are made up of hard spheres that are in random motion.

Explanation:

A gas is a <u>state of aggregation of matter</u> in which, under certain conditions of temperature and pressure, <u>its molecules interact weakly with each other, without forming molecular bonds</u>, adopting the shape and volume of the container that contains them and tending to separate everything possible because of its <u>high concentration of kinetic energy</u>.

The molecules of a gas are practically <u>free</u> and have the ability to be distributed throughout the space in which they are contained because <u>the gravitational forces and attraction between them are practically negligible</u> compared to the speed at which they move. .

Therefore, gas molecules do not travel specific trajectories or vibrate in a stationary position, instead <u>they move quickly and randomly through the entire space of the container that contains them.</u>

How is aluminum used in a lithium ion type of battery?
r-ruslan [8.4K]

Answer:

Explanation:

Aluminium is used in rechargeable battery.

Aluminium ions provide the energy by flowing from anode to the cathode.

When the battery is recharged these ions comes to the anode.

The one ion gives three electrons. Which means one Al⁺³ is equal to the three Li⁺ ions. So, three unit of charge giving by ions increase the energy storage capacity.

The rechargeable batteries with aluminium gives low cost and low flammability.

It is safe to use because of inertness of aluminium and also easy to use in ambient environment.

Aluminium also have high volume capacity than lithium which means energy storage per volume is greater.

Its charge discharge cycles are also greater.

The aluminum ion batteries are also smaller in size.

Suppose the data formed a line with a steeper slope. For the same change in temperature, how would the change in volume compare?
bogdanovich [222]
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.
