Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
(c) Gases have no definite volume and no definite shape. Solution : (a) Solids have definite shape and definite volume because the molecules in solid are closely packed and in fixed positions. The molecules can vibrate but do not move around which keeps the shape and volume definite.
A solid has a definite shape and a definite volume. The particles that make up a solid are packed very closely together. Each particle is tightly fixed in one position and can only vibrate in place.
Liquids. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
A. A solid has a fixed shape and volume that do not change with the shape of its container. Consider a rock and how its size and shape stay the same, regardless of where you put it. A liquid has a constant volume, but its shape conforms to the shape of its container.
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant.
gas
Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.
Matter is made of small particles of atoms or molecules. There are three common states of matter, solid, liquid and gas. A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container.
Matter in the gaseous state has both variable volume and shape, adapting both to fit its container. Its particles are neither close together nor fixed in place.
Gases
Matter cannot be created or destroyed in a chemical reaction; it is rearranged. The number of each different elements remains the same. Yet, after the reaction, an element may link to one element that is different from the one it links to before the reaction.
To manufacture matter in a way that adheres to the first law of thermodynamics, you have to convert energy into matter. So yes, humans can manufacture matter. We can turn light into subatomic particles, but even the best scientists can’t create something out of nothing.
“Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist,” Hawking writes. “It is not necessary to invoke God to light the blue touch paper and set the universe going.”
Quantum mechanics tells us that there is no such thing as empty space. Even the most perfect vacuum is actually filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness.
