Determine whether heating or cooling takes place during each process:

Biology
1 answer:
MakcuM [25]3 years ago
5 0

Explanation:

EVAPORATION                                   heating

CONDENSATION                                cooling

FREEZING                                            cooling

MELTING                                              heating

SUBLIMATION                                      heating

DEPOSITION                                      not a phase change

EVAPORATION

This is a phase change process in which liquids are converted into gases by the addition of heat to them. When liquid water changes to water vapor, it has been evaporated. This occurs beyond the boiling point of matter.

CONDENSATION

Condensation is a phase change in which gases are cooled to liquid. It involves the liquid coming in contact with a cold source. The hot gas loses heat to the cold material.

FREEZING

It is a phase change in which liquids changes to solids by the removal of heat from them.

MELTING

This is a phase change in which a solid changes to liquid when more heat is added.

SUBLIMATION

This is a phase change in which a solid changes to gas with the addition of heat.

Deposition is not a phase a change.

1. ¿Qué es la sociedad civil? ¿Quiénes la conforman? ¿Por qué es importante para la democracia?
Novay_Z [31]

Answer:

La sociedad civil también se llama tercer sector de la sociedad.

Explicación:

La sociedad civil es un tipo de sociedad que se compone de personas que exigen los derechos y deseos del público. También se le llama tercer sector de la sociedad porque es diferente del sector gubernamental y empresarial. Las personas del sector familiar y privado conforman la sociedad civil. Es importante para la democracia porque proporciona control y equilibrio sobre la democracia y evita que el gobierno tome malas decisiones.

Which of the following best describe gas particles?
timama [110]

Answer:

a, b, d (see below)

Explanation:

So, looking at the 3 states of matter:

Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)

Liquid - holds shape of its container and has particles with some space in between them that allow them to flow

Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around

Refer to the image below for a better visual understanding.

So, now, looking at the answer choices:

a) moving randomly

Yes. They are—they're speeding around super fast all the time.

Every time heat is added to something, the particles start loosening up and moving.<em> A lot.</em>

So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.

Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves <em>super fast</em>

<em />

b) collide into each other

Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.

Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.

c) move slow

No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.

d) high kinetic energy

Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.

Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.

e) moving orderly

No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.

(refer to my bumper car example in answer b, in bold)

DNA bases pair up in a specific way. In your own words, describe the base-pairing rules in any
joja [24]
Adenine always pairs with Thymine, and Cytosine always pairs up with Guanine in DNA. When dealing with RNA, however, Uracil replaces Thymine. So in RNA, A pairs with U and C pairs with G. (just a fun fact) :)
