What determines the state of a substance?
The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state. A gas is a state of matter in which atoms or molecules have enough energy to move freely.
What determines whether a substance is a solid liquid or gas?
Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.
What factor is most important in determining whether water is a solid liquid or gas?
Temperature
How can you say that one substance is different from another?
Different substances have different properties; density is one property that can be used to tell two substances apart. Density is a property that does not depend on the shape or size of an object.
What are the properties of solids liquids and gases?
There are three common states of matter:
- Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other.
- Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded.
- Gases – no definite volume or shape.
What are the three properties of solids liquids and gases?
solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
What are the 3 properties of gases?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.
What are the 5 properties of gases?
What Are Five Properties of Gases?
- Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states.
- Indefinite Shape or Volume. Gases have no definite shape or volume.
- Compressibility and Expandability.
- Diffusivity.
- Pressure.
What are the 6 properties of gases?
Properties of Gases
- What are the Properties of Gases? Gasses do not possess any definite volume or shape.
- Compressibility. Particles of gas have huge intermolecular spaces in the midst of them.
- Expansibility. When pressure is exerted on gas, it contracts.
- Diffusibility.
- Low Density.
- Exertion of Pressure.
What are the two properties of liquid?
All liquids show the following characteristics:
- Liquids are almost incompressible. In liquids molecules are pretty close to each other.
- Liquids have fixed volume but no fixed shape.
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
What is matter write two properties of solid and two properties of liquids?
MATTER – Anything that occupies space and have somemass and volume is known as matter. two properties of liquid are, have no definite shape and not disturb boundaries if I fill it in a container it will take shape of the container. Properties of solids include: Definite shape and volume.
What two properties do liquids and gases have in common?
(i) Both of them donot have any definite shape. They can take up the shape of the container in which these are kept. (ii) Both of them show the property of diffusion.
What are the properties of liquid pressure?
The characteristics of liquid pressure are:
- Liquid pressure increases with depth.
- Liquid pressure remains the same in all directions at a given depth.
- Liquid pressure depends upon the density of the liquid.
- Liquid exerts pressure on the sides of the container.
- A liquid seeks its own level.
What is the difference between atmospheric pressure and liquid pressure?
The difference is that water is an incompressible fluid — its density is almost constant as the pressure changes — while air is a compressible fluid — its density changes with pressure. Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it.
What are properties of pressure?
Therefore, pressure is a scalar quantity, not a vector quantity. It has magnitude but no direction sense associated with it. Pressure force acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular (at right angle) to the surface.
What are the laws of liquid pressure?
1) liquid exerts pressure on the wall of container. 2) pressure force increases as the depth of liquid increases. 3) pressure force will be same at all points inside the liquid at equal depth.
What are the five laws of liquid pressure?
(i) Pressure at a point inside the liquid increases with the depth from its free surface. (ii) In a stationary liquid, pressure is same at all points on a horizontal plane. (iii) Pressure is same in all directions about a point in the liquid. (iv) Pressure at same depth is different in different liquids.
What are the consequences of liquid pressure?
Common consequences of fluid pressure – example 1. Difficulty in breathing at high altitudes. 2. Divers often feel pain in ears as the eardrums compress due to the high pressure in sea at high depths.
