A liquid contains 30 billion particles. How many particles will it contain when turned into a solid?

cupoosta [38]2 years ago

When it turns into a solid, the liquid will contain the same 30 billion particles.

We can arrive at this answer because:

  • Changing the states of matter does not change the composition of substances.
  • In this case, if a substance changes its matter to liquid, solid or gaseous, the composition of that substance will remain the same after the change of physical state.
  • What changes between these changes is the way the particles are arranged.

Based on this, we can say that if a liquid substance contains 30 million particles and turns into a solid substance, the 30 million particles will be kept, but the arrangement between them will be modified.

In a solid substance, the particles will form a stable arrangement, with little space between them and without the possibility of movement between them.

Which correctly describes the term demographic transition?
zavuch27 [327]

Answer:

The transition from high birth rates and death rates to low birth rates and death rates as a country develops.

Explanation:

Demographic transition tend to occurs when a country become more economically developed.

When a country is considered as 'undeveloped' , the amount of mortality that occurs in the country tend to be really high. Mostly due to illness ( lack of medical development to cure it) , Conflicts, and accidents due to unsafe workplace environment. To balance it out, Government tend to encouraged the couples in the nation to have more children.

As the country progress death from illness, conflict and unsafe regulations tend to be heavily reduced. This will reflected into the very low death rates in the country. As the couples in a developed nations now put more focus on self-actualization, they will become less likely to have many children. This will lead to low birth rates in that country.

How does a sod house compare to the house in which you live? Identify at least two advantages
Lostsunrise [7]

The correct answer to this open question is the following.

How does a sod house compare to the house in which you live?

It really can be compared because a sod house was more like a cabin, a country house in colonial times, like the ones built in the Northeast colonies, made of wood. Just like the ones built in the frontier plains of the United States territory and Canada.

Identify at least two advantages your house has over one made of sod.

My house is bigger, more rooms, more space in each room, and it's comfy.

The two advantages that a sod house had over one built like yours could be that the sod house is made of wood, a natural material that really keeps the interior of the house cool and fresh during the hot summer days, and relatively warm with the help of a chimney during the cold weather of the winter season. The other advantage could be that is located in the country. So you leave your house and you see the forest, trees, probably creeks, instead of concrete streets, highways, noise, and polluted air, as in the case of a house in the city.
