Compare and contrast the arrangement of particles at the atomic level for a liquid and a solid

Chemistry
1 answer:
galben [10]3 years ago
5 0

Answer:

Liquid particles are farther apart than solid particles.

Explanation:

Liquid particles are more far apart than solid particles, explaining why it takes the shape of its container and does not have a definite shape, but has a definite volume. Solid particles are more tightly packed together, and certain solids even have particle patterns at the atomic level, which is why it has a definite shape and does not change unless it changes states.

Why earth not flat and why we live in this country not yours
bagirrra123 [75]

Answer:

Earth is not flat because the spheroidical shape provides a more effective shape in terms of exposed surface area for absorbing and radiating radiation, and also for a relatively more uniform gravity pull on different points on its surface which might not be so for a flat surface.

You live in your country, not mine because you have evolved over time to be more adapted to living in your own kind of envoirment. Members of a certain species (like you and me as humans) have been spread to maximize the survivability of their species compared to if they were clustered to a particular place.

How many miles of a gas sample are in a 20.0 l container at 373kand 203 kpa? the gas constant is 8.31 l-kpa/m-k
ladessa [460]
To simplify our solution for this probelm we first assume that the gas we are dealing with is an ideal gas. Given that it is ideal we can proceed the solution using the formula: PV=nRT where P is pressure (203KPa), V is volume (20.0 L), n is moles (required), T is absolute temperature (373K) and R is the gas constant ( <span>8.31 l-kpa/m-k). Plug in the given to the respective variables and you should get 3.28 moles of the gas sample. </span>

Which statement about fusion reactors is true? a Enriched uranium isotopes are used as fuel in fusion reactors. b Fuel for fusio
trapecia [35]

Answer:

b Fuel for fusion reactors can be extracted from ocean water.  

Explanation:

The fuel is deuterium, which makes up 0.02% of the hydrogen atoms in water. The oceans contain more than a billion cubic kilometres of water, so that's a lot of deuterium.

a is wrong. The fuel for fusion reactors is deuterium.

c is wrong.  There is much research, but there are no large-scale fusion reactors in operation.

d is wrong. Fusion reactors do not produce radioactive waste as spent fuel. Most of the radioactive waste would be the reactor core itself.

Significant figures are a measure of __________. an precise and accurate answer. the true value of a measurement. accuracy. prec
34kurt

Answer:

Significant figures are a measure of <u><em>precision</em></u>.

Explanation:

The significant figures of a number are those that have a real meaning and, therefore, provide some information. Therefore, the set of digits that are known with certainty in a measure are called significant figures and are the digits of a number considered non-null.

Any experimental measurement is inaccurate and must be expressed with its significant figures.

In this way, significant figures express the precision of a measuring tool.
