You have been handed a 1892.6g sample of Rion and determine that it has
a volume of 200.0 mL. What is the density of Rion?
Answer:
9.46 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 1892.6 g
volume = 200 mL
We have
[tex]density = \frac{1892.6}{200} \\ = 9.463[/tex]
We have the final answer as
9.46 g/mLHope this helps you
Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer
A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

what is the relationship between temperature and pressure pls
Answer:
When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.
Answer:
We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.

What is solar system?Solar system is defined as the grouping of the eight planets and their moons in orbit around the sun, as well as other smaller bodies like comets, asteroids, and meteoroids.
It can also be defined as the Sun's orbiting objects are confined by gravity to one system.
An orbiting collection of planets, meteors, or other celestial bodies is referred to as a star system.
The Sun, an ordinary star, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto make up our solar system.
Our solar system is referred to as the "solar system" because our Sun is called Sol after the Latin word for Sun, "solis," and because anything related to the Sun is termed "solar."
Thus, scientists work independently to form theories about the Earth without sharing data.

Use the information about igneous rocks A-D to classify each one as intrusive or extrusive and basaltic or granitic. Fill in the
chart with A, B, C, or D.
Rock A-dark-colored large grains
Rock B-large crystals, high percentage of silica
Rock C-fine-grained texture, light-colored
Rock D—from Hawaiian volcano area, no visible crystals
Extrusive

2.
Basaltic
Granitic
3.
4.
Answer:
1. D 2.. A 3. C 4. B
Explanation:
just took the quiz
We can classify each rock as intrusive or extrusive and basaltic or granitic as follows; Rock A - Extrusive, Basaltic, Rock B - Intrusive, Granitic, Rock C - Extrusive, Basaltic, and Rock D - Extrusive, Basaltic.
Rock A - Extrusive, Basaltic
Rock A is described as having dark-colored large grains, which indicates a fine-grained texture, typical of extrusive rocks. The presence of dark-colored large grains suggests a basaltic composition.
Rock B - Intrusive, Granitic
Rock B is described as having large crystals and a high percentage of silica, which suggests a coarse-grained texture, typical of intrusive rocks. The high silica content and large crystals indicate a granitic composition.
Rock C - Extrusive, Basaltic
Rock C is described as having a fine-grained texture and being light-colored, which are characteristic features of extrusive rocks. The fine-grained texture suggests a rapid cooling, typical of extrusive rocks, and the light color is indicative of a basaltic composition.
Rock D - Extrusive, Basaltic
Rock D is described as being from the Hawaiian volcano area and having no visible crystals. This indicates a glassy texture, typical of rapidly cooled extrusive rocks. The origin from a volcanic area and glassy texture suggest a basaltic composition.

Back injuries can be crippling and severely limit one’s function and quality of life.
How would your life be affected by a back injury?
What modifications would you have to make to your home if you were confined to a wheelchair?
Which of your hobbies and activities would be affected if you could no longer walk?
A back injury would impact literally every aspect of your life.
You would need to either install a starlit, a lift, or move to a bungalow or bottom floor apartment.
The only hobbies you would be able to complete with no modifications would be what I call stationary hobbies- when you sit and do something, for example, knitting or sewing. However, some sports can be altered to allow for those in a wheelchair to play.

Explanation:
cracks in the road: the road expand on heating
hot air balloons: Because the hot air inside the balloon bag increases in size faster than the container it stretches the bag so that it expands and displaces the colder (heavier) air outside the bag
tire bursts in hot days when filled full of air due to thermal expansion

what is the strongest intermolecular force to be overcome when ethanol is converted from a liquid to a gas?
Answer:
hydrogen bonding
Explanation:
The strongest among them is hydrogen bonding, and the weakest are London dispersion forces.
The strongest intermolecular force to overcome when ethanol is converted from liquid to a gas is hydrogen bonding.
Intermolecular forces are forces that are a weaker force of attraction than intramolecular forces.
Intermolecular forces are forces between molecules and hold these molecules together.
Hydrogen bonding is an example of intermolecular forces between the OH group in the alcohol.
During the conversion of ethanol from liquid to gas state, hydrogen bonding occurs between the partial negative charge in the oxygen and the partial positive charge in the hydrogen.
