How are green house gases made?
Gases are made when you heat up solids or liquids. Liquids are made when you cool down gases or heat up solids. Solids are made when you cool down gases or solids. When you heat up solids they make liquids and when you heat up liquids it makes gases. When you heat up gases it makes plasma (plas-mu) but that is very very very very very very hard to make.
What material does sound travel the fastest?
Sound travels the fastest in solids. Solids being the most denser make sound travel fastest as compared to liquids and gases which have speed of sound relatively less than solids.
What properties do gases have that liquids dont?
In a solid. There are a WHOLE lot of particles. They are all tightly connected and the only way to separate them is by using a lot of force. In a liquid, the particles are connected but can move around freely. They still have to connect to the other particles, but the bond is weaker and very easily broken. In a gas, the particles are NOT connected and can move around freely. They do not have to be connected, unlike solids and liquids; and they can move, unlike solids.
Do liquids expands when heated?
Only one liquid expands when heated and thats water the most common liquid.
When solid changes into liquid?
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
If cooled does most solids change into gases?
No, cooling solids typically causes them to contract and become denser, rather than changing into gases. Cooling a substance lowers the kinetic energy of its molecules, which reduces the distance between them and causes the solid to solidify further. However, if the solid sublimes (changes directly from solid to gas), then cooling could cause it to transition into a gas.
What state of matter expands the most on heating?
Solids, liquids and gases expand when heated, liquids and gases expand much more that solids. Gases can be compressed
Why do you think it is easier to find solids then liquids and gases?
I think because mostly it is solids that are all around you, and what you notice the most. So you don't really pay attension to liquids or gases unless your handling them.
What is diffusion in liquid and in gas?
Gases the most, then liquids. Solids generally don't diffuse.
What is the most condensed state of matter?
The most condensed state of matter is a Bose-Einstein condensate (BEC). BECs are formed at extremely low temperatures near absolute zero, where atoms behave as a single quantum entity, exhibiting wave-like properties. This state allows for the observation of quantum phenomena on a macroscopic scale.
Why solids do not mix well but gases and liquids mix easily in most cases?
Solids have a fixed shape and volume, making it difficult for them to mix as their particles are tightly packed and have limited mobility. In contrast, gases and liquids are more mobile with particles free to move around, allowing for easier mixing due to their fluid nature. Additionally, gases and liquids have the ability to flow and fill the space of their container, promoting mixing.
Are liquids dense?
Yes, liquids have a density, which is a measure of how closely packed the molecules are in the liquid. The density of a liquid can vary depending on its temperature and composition.
Do liquids have high or low density?
It depends on the liquid. Some liquids, like water, have relatively high density compared to other liquids like oil or alcohol. Density is a measure of how much mass is contained within a specific volume, so liquids with higher density have more mass packed into a given volume.
Why are gases not always visible while most liquids and solids are visible?
It's mostly to do with density. In simple terms, gases have very low densities compared to solids and liquids, so that their molecules/atoms cause very little scatting of light as it passes through them.
Why do solids not mix well but gases and liquids mix well easily in most cases?
Solids have tightly packed atoms so there is no space for the atoms to mingle. But in liquids/ gases, the atoms are more spread out and more free to move hence allowing the atoms to mingle.
Why do liquids have greater volatility than solids?
You mean like mercury and frozen carbon dioxide? In most cases you're correct, but that's because -in general- liquids are closer to being gases than are solids.
How are green house gases made?
Gases are made when you heat up solids or liquids. Liquids are made when you cool down gases or heat up solids. Solids are made when you cool down gases or solids. When you heat up solids they make liquids and when you heat up liquids it makes gases. When you heat up gases it makes plasma (plas-mu) but that is very very very very very very hard to make.
